Revert "ALSA: hda: Fix page fault in snd_hda_codec_shutdown()"
commit 53f07e9b010b966017e32be1ca1bbcbcc4cee73d upstream. This reverts commit 980b3a8790b402e959a6d773b38b771019682be1. The commit didn't consider the fact that ASoC hdac-hda driver initializes the HD-audio stuff without calling snd_hda_codec_device_init(). Hence this caused a regression leading to Oops. Revert the commit to restore the behavior.
