ALSA: hda - Fix pending unsol events at shutdown

Browse source

This is an alternative fix attemp for the issue reported in the commit
caa8422d01 ("ALSA: hda: Flush interrupts on disabling") that was
reverted later due to regressions.  Instead of tweaking the hardware
disablement order and the enforced irq flushing, do calling
cancel_work_sync() of the unsol work early enough, and explicitly
ignore the unsol events during the shutdown by checking the
bus->shutdown flag.
