Piotr Pryga 3715241bde Bluetooth: Controller: fix per sync hang if wrong cte and list filter
In case of use of filtering based on: periodic advertising list and
CTE type, the synchronization can hang. That is possible if a periodic
advertiser uses wrong CTE type. In such situation the sync is not
released in ull_sync_done call. What more the sync->timeout_reload
is not cleared and Host is not able to cancel the synchronization.
The periodic advertising is in a semi-sync-established state.
There are no reports send to Host. Host can't use the sync set to
synchronize with other device. It is only able to terminate the
sync (call to ll_sync_terminate).

To fix the issue following changes should be applied:
- isr_rx_adv_sync_estab should call isr_rx_done_cleanup
with sync_term parameter in case the sync_ok isn't SYNC_STAT_ALLOWED.
In any case the CTE type is wrong, no matter is the periodic
advertising list filtering is enabled or not.
- ull_sync_established_report should set sync->is_term to true
in case the CTE type is not allowed. That change is required for devices
that do not support Direction Finding Extension. For those devices CTE
type based filtering is done in ULL by ull_sync_established_report
function. The sync->is_term should be set unconditionally, hence is
moved up in the function.

With these two changes done, ull_sync_done function will execute
sync_ticker_release in case the CTE has wrong type. ULL, depending on
notifications prepared by ull_sync_established_report, will follow up
on sync termination if required.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
