ALSA: pcxhr: Fix missing mutex unlock
[ Upstream commit 67f3754b51f22b18c4820fb84062f658c30e8644 ]
The commit [9bef72bdb26e: ALSA: pcxhr: Use nonatomic PCM ops]
converted to non-atomic PCM ops, but shamelessly with an unbalanced
mutex locking, which leads to the hangup easily. Fix it.
Fixes: 9bef72bdb26e ('ALSA: pcxhr: Use nonatomic PCM ops')
