Subject: [PATCH] [UBUNTU:sound/core/] Fix pcm-draining of capture stream in PCM middle layer

UpstreamStatus: Added in upstream alsa-kernel hg changeset 912de5ce9d3c
                http://hg-mirror.alsa-project.org/alsa-kernel?cmd=changeset;node=912de5ce9d3c7f5959b9e2c0b8472237e4cda77e;style=raw

Fix the draining of PCM capture stream in the PCM middle layer.
snd_pcm_drain() ignored capture streams, but it should change the state
to SNDRV_PCM_DRAINING.
