Pierre-Louis Bossart ac3467ad7f ALSA: hda: ext: fix locking in stream_release
The snd_hdac_ext_stream_release() routine uses the bus reg_lock, but
releases it before calling snd_hdac_stream_release() where the bus
reg_lock is taken again.

This creates a timing window where the link stream release could test
an invalid 'opened' boolean status and fail to recouple the host and
link parts.

Fix by exposing a locked version of snd_hdac_stream_release() and use
it without releasing the spinlock.
