[alsa-devel] [PATCH alsa-lib] pcm: dmix: Don't ignore SND_TIMER_EVENT_MSTOP

When a slave PCM gets an error like XRUN, it stops and notifies with
SND_TIMER_EVENT_MSTOP event.  But the current code filters out this
type and eventually hang due to the empty timer queue.  The fix is to
just add this event type to the filter bit mask.
