ALSA: hda/hdmi: Fix incorrect mutex unlock in silent_stream_disable()
The silent_stream_disable() function introduced by the commit
b1a5039759cb ("ALSA: hda/hdmi: fix silent stream for first playback to
DP") takes the per_pin->lock mutex, but it unlocks the wrong one,
spec->pcm_lock, which causes a deadlock. This patch corrects it.
