ALSA: snd-meastro3: Ignore spurious HV interrupts during suspend / resume

commit 715aa675338ce6e1a3b4f77cf87ea611f93058a8 upstream.

Ignore spurious HV interrupts during suspend / resume, this avoids
mistaking them for a mute button press. This is not very pretty but
it seems the only way to fix the master volume control gets muted
after suspend issue I'm seeing. Note that the es1968 driver is doing
exactly the same.
