[PATCH] ALSA: pcm: Apply sync-stop at SNDRV_PCM_IOCTL_DROP ioctl

[Takashi Iwai <tiwai@suse.de>]

When a PCM stream is stopped via SNDRV_PCM_IOCTL_DROP ioctl, it calls
snd_pcm_stop() but sync-stop operation is missing.  Although this is
usually no big issue, let's add snd_pcm_sync_stop() call, just to be
sure.
