Chris Wilson 8b18e0e24d ALSA: hda: Flush interrupts on disabling 
[ Upstream commit caa8422d01 ]

which has the hallmarks of a worker queued from interrupt after it was
supposedly cancelled (note the POISON_FREE), and I could not see where
the interrupt would be flushed on shutdown so added the likely suspects.
