ALSA: hda - Fix / clean-up slave digital out codes
The recent slave_dig_out addition has some rooms to clean up. Also it doesn't call snd_hda_cleanup_stream() properly for slaves at closing. The patch fixes both issues. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
