ALSA: hda: Fix codec device field initializan
Commit f2bd1c5ae2cb ("ALSA: hda: Fix page fault in
snd_hda_codec_shutdown()") relocated initialization of several codec
device fields. Due to differences between codec_exec_verb() and
snd_hdac_bus_exec_bus() in how they handle VERB execution - the latter
does not touch PM - assigning ->exec_verb to codec_exec_verb() causes PM
to be engaged before it is configured for the device. Configuration of
PM for the ASoC HDAudio sound card is done with snd_hda_set_power_save()
during skl_hda_audio_probe() whereas the assignment happens early, in
snd_hda_codec_device_init().
Revert to previous behavior to avoid problems caused by too early PM
manipulation.
