From: Di Wu <di1028...@samsung.com>
Multi-thread decoding doesn't work when refreshctx is equal to 0. Fix
it by call ff_thread_finish_setup function in the condition when
refreshctx is equal to 0.
In vp9_decode_frame function, ff_thread_finish_setup is not called
when refreshctx is equal to 0. The next decoding thread can not
start work until the cunrrent frame has been decoded completely. So
multi-thread decoding in frame level is not enabled when refreshctx
is equal to 0.
