Potential deadlock in V4L2SliceVideoDecodeAccelerator

Project Member Reported by wuchengli@chromium.org, Sep 10 2016 
It seems there's a potential deadlock in V4L2SliceVideoDecodeAccelerator.
- Decoder thread calls FinishSurfaceSetChange->DestroyOutputs and waits on  DismissPictures to finish in child thread. (#1)
- Child thread calls Destroy and waits decoder thread to stop. (#2)
