Su Hui 79597c8bf6 ALSA: ac97: Fix possible NULL dereference in snd_ac97_mixer 
smatch error:
sound/pci/ac97/ac97_codec.c:2354 snd_ac97_mixer() error:
we previously assumed 'rac97' could be null (see line 2072)

remove redundant assignment, return error if rac97 is NULL.

Fixes: da3cec35dd ("ALSA: Kill snd_assert() in sound/pci/*")
