Subject: [PATCH] vp9: enable multi-thread decoding when refreshctx is equal to
 0

In vp9_decode_frame function, ff_thread_finish_setup is not called
when refreshctx is equal to 0, and the next decoding thread can not
start work until the cunrrent frame has been decoded completely. So
ff_thread_finish_setup needs to be called to enable Multi-thread
decoding in this condition.
