ALSA: hda: Fix put_device() inconsistency in error path

Browse source

AVS HDAudio bus driver does not tie with codec drivers tighly. Codec
device and its respective driver cleanup procedures are split and may
not occur one after the other. Device cleanup is performed only on
snd_hdac_ext_bus_device_remove() i.e. it's the bus driver's
responsibility. If codec component probing fails, put_device() found in
snd_hda_codec_device_new() may lead to page fault. Relocate it to
snd_hda_codec_new() to address the problem on ASoC side while keeping
status quo for snd_hda_intel.
