ULL reference count is checked in ULL_LOW context to decide
if LLL events are pending, but the reference count can be
decremented by the ULL HIGH execution context which can
prevent the set `disabled_cb` function not being called due
to no pending event to produce the done events.
Fixed by checking the reference count in the ULL HIGH
execution context using a mayfly to schedule the check.

Handling of HCI_LE_Periodic_Advertising_Sync_Established didn't
have implemented handling of possible failures of periodic
advertising synchronization.
There are two situations definded by BT 5.3 Core spec:
- There is no AUX_SYNC_IND pdu within 6 periodic advertising events.
If that happens, status of the command is set to (0x3E) Connection
Failed To Be Established / Synchronization Timeout.
- Periodic advertising has wrong CTE type while periodic advertising
list is not used to determine the advertiser to listen.
In this case status of the command is set to (0x1A) Unsupported
Remote Feature.
The commit provides missing functionality.
In case of error, the periodic advertising will be deleted and
application will be notified by call to terminated callback.
The callback data were extended by err member. It provides
information why periodic advertising was terminated.
