ALSA: hda: ext: simplify logic for stream assignment
The logic is needlessly complicated, the basic rule is:
The host streams can be found by checking the 'opened' boolean.
The link streams can be found by checking the 'link_locked' boolean.
Once a stream is found, it can be unconditionally decoupled. The
snd_hdac_ext_stream_decouple_locked() routine will make sure the
register status is modified as needed and the 'decoupled' boolean set.
