ALSA: compress: fix partial_drain completion state
On partial_drain completion we should be in SNDRV_PCM_STATE_RUNNING state, so set that for partially draining streams in snd_compr_drain_notify() and use a flag for partially draining streams While at it, add locks for stream state change in snd_compr_drain_notify() as well.
