Bluetooth: Controller: Fix assertion terminating Periodic Sync (32637290) · Commits · Wenxi XU / zephyr

Fix assertion due to changes introduced to support multiple advertising chain reception. Auxiliary context association with the Periodic Sync context was not cleared due to which when terminating a Periodic Synchronization triggered an assertion check, under race conditions, detecting that the auxiliary context was already released.
