ALSA: hda/ca0132 - Keep power on during processing DSP response
We need to keep power on while processing the DSP response via unsol
event. Each snd_hda_codec_read() call does the power management, so
it should work normally, but still it's safer to keep the power up for
the whole function.
Fixes: a73d511c4867 ("ALSA: hda/ca0132: Add unsol handler for DSP and jack detection")
