ALSA: hda - Fix registration race of VGA switcheroo
commit 128960a9ad67e2d119738f5211956e0304517551 upstream.
Delay the registration of VGA switcheroo client to the end of the
probing. Otherwise a too quick switching may result in Oops during
probing.
Also add the check of the return value from snd_hda_lock_devices().
