This fixes a bug where the stack may get stuck in the
POWER_CLOCK ISR after enabling and disabling the Bluetooth
stack a couple of times. It happens after calling
`onoff_request()` after a failing call to `onoff_release()`.
Then the `lf_cli`s next points to itself, generating a
circular list of clients.
Calling `onoff_release()` may fail if there is an outstanding
request. By calling `onoff_cancel()` we enter a state where
we can safely remove the client.
This was not seen earlier because the return value
from `ll_deinit()` in `hci_driver_close()` was ignored.

ull_adv_sync_pdu_set_clear does pretty much everything, causing

It has been replaced with simpler, more complete functions for handling
the relevant operations

- Fragmentation of adv data over HCI is now decoupled from PDU
fragmentation, fixing HCI/DDI/BI-13-C, LL/DDI/ADV/BV-26-C and
LL/DDI/ADV/BV-55-C
- Adding BigInfo now preserves the PDU chain

In ull_disable, it is imperative that the callback is set up before a

event has already passed when the disable callback and semaphore is

This causes the HCI thread to wait until timeout and assert after
