ALSA: hda: Honor PM disablement in PM freeze and thaw_noirq ops

Browse source 
commit 10db5bccc390e8e4bd9fcd1fbd4f1b23f271a405 upstream.

freeze_noirq and thaw_noirq need to check the PM availability like
other PM ops.  There are cases where the device got disabled due to
the error, and the PM operation should be ignored for that.

Fixes: 3e6db33aaf ("ALSA: hda - Set SKL+ hda controller power at freeze() and thaw()")
