There is a test that verifies a behavior of CTE request control
procedure if receives LL_UNKNOWN_RSP. The expected behavior
is to terminate connection if that is response handling is
not implemented by a command. Other unexpected responses are
treated as new remote control procedures.
The CTE request has implemented handling of LL_UNKNOWN_RSP,
hence this particular test is no longer valid.
There is still open question how to handle other unexpected
reposne PDUs while waiting for LL_CTE_RSP. That is not defined
by BT 5.3. Core specification and not decided by community.
The test is removed to because it fails and blocks CI.

CTE request tests were not working because there was missing
a code that sets conn.llcp.cte_req.is_enabled flag.
If the flag is not set, then the CTE request state machine
comletes its execution immediately as if the request was
disabled by Host in the meantime.
Signed-off-by: Piotr Pryga <piotr.pryga@nordicsemi.no>
The periodic CTE_REQ disable command, requested by Host, may be locked
until connection is dropped due to missing CTE_RSP from peer device.
That is caused by implementation of CTE_REQ disable and CTE_REQ
control procedure handling.
The procedure is marked as active when CTE request was send to peer
device. It is marked as inactive after completion of the procedure.
That caused locking of CTE disable on a semaphore.
The BT 5.3 Core Spec, Vol 4, Part E, section 7.8.85 says the HCI_LE_-
Connection_CTE_Request_Enable should be considered active on a conne-
ction from when Host successfully issues the command with Enable=0x1
until a command is issued with Enable=0x0 or single LLCP CTE request
has finished (CTE_Request_Interval=0x0). Also there is a clarification
from BT SIG that the command with Enable=0x0 does not affect any
initiated LLCP CTE request. That means Controller is allowed to finish
already started procedure and it is not allowed to start new LLCP CTE
request procedure after completion of the command with Enable=0x0.
Taking that into account, there is no need to synchronize ULL and LLL
in regard of disable the LLCP CTE request while the procedure is
pending. Controller is free to complete the procedure or terminate it.
The change removes all code related with cte_req.is_active, disable
callback and waiting of ULL for LLL to finish the LLCP CTE request.
The ULL will complete the HCI_LE_Connection_Request_Enable with
Enable=0x0 immediately. In case the procedure is disabled in before
the response arrives, then further processing of the response is
dropped and the procedure context released.
The context is not released by the code responsible for disable
handling, to have single place where it is done.

llcp_lr_pause()/llcp_rr_pause() only pauses currently pending procedures
in their respective request machines, any future initiations are not
paused, thus they are allowed to run, when the opposite was expected.
Change the procedure pause logic into a global pause on the request
machines them self, this is essence what the per-procedure pause
flag was trying to achieve.
Add new query function llcp_?r_ispaused() to not expose the logic behind
the pause functionality.

number of expected free procedure context objects. It was expected

Connection update procedure
Channel map update procedure
Encryption procedure
Feature exchange procedure
Version exchange procedure
ACL termination procedure
Connection parameters request procedure
LE Ping procedure
Data Length Update procedure
