ALSA: hda/ca0132 - Keep power on during processing DSP response 

commit 377bc0cfabce0244632dada19060839ced4e6949 upstream.

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.
