Pierre-Louis Bossart 293385739d ALSA: hda: hdac_ext_stream: fix potential locking issues
commit 868ddfcef31ff93ea8961b2e81ea7fe12f6f144b upstream.

The code for hdac_ext_stream seems inherited from hdac_stream, and
similar locking issues are present: the use of the bus->reg_lock
spinlock is inconsistent, with only writes to specific fields being
protected.

Apply similar fix as in hdac_stream by protecting all accesses to
'link_locked' and 'decoupled' fields, with a new helper
snd_hdac_ext_stream_decouple_locked() added to simplify code
changes.
