Fix regression in central initiated terminate introduced in
commit 3a80785947 ("Bluetooth: controller: Fix connection
terminate to happen on event done").
The regression caused an additional central connection event
transmitting PDU after the previous connection event had
received acknowledgment for the terminate_ind PDU from the
peripheral.

Avoid using sizeof to access ULL and LLL struct members.
Based on the alignment requirements of structures, due to
padding between structure members, use of sizeof of previous
struct member to access next struct member is incorrect.
Continue to use explicitly stored parent pointer to access
ULL context. Combine event header and ULL header so that
the parent pointer point directly to the combined ULL
struct.

Fix missing initialization of reference count in
ull_hdr_init function.
This has not caused issues so far, but when the ref member
of the struct ull_hdr if placed in the beginning of a
context that is allocated using mem_acquire function then
first few bytes used would make the ref member to have
uninitialized value when such context is allocated by
mem_acquire. First few bytes are the next pointer and free
count stored by the mem module.
The issue was discovered in subsequent commits that
restructure the ULL context structures.

In the time between a NODE_RX_TYPE_CONNECTION node is sent from LLL and
demuxed in ULL, an ADV role disable may be executed.
This makes the LLL data referenced in the node NULL/invald, and
ull_conn_setup would operate on invalid data.
This commit introduces a check in ADV disable to disallow the operation
(including conn invalidation), if a connection has been initiated.
To prevent pipeline-queued prepares from advertising after disable has
been initiated, set 'cancelled' flag for immediate signalling to LLL.
