The unsolicited event handler for the headphone jack on CA0132 codec driver tries to reschedule the another delayed work with cancel_delayed_work_sync(). It's no good idea, unfortunately, especially after we changed the work queue to the standard global one; this may lead to a stall because both works are using the same global queue. Fix it by dropping the _sync but does call cancel_delayed_work() instead. Fixes: 993884f6a26c ("ALSA: hda/ca0132 - Delay HP amp turnon.")
