media: s5p-mfc: Fix to handle reference queue during finishing
commit d8a46bc upstream. On receiving last buffer driver puts MFC to MFCINST_FINISHING state which in turn skips transferring of frame from SRC to REF queue. This causes driver to stop MFC encoding and last frame is lost. This patch guarantees safe handling of frames during MFCINST_FINISHING and correct clearing of workbit to avoid early stopping of encoding.
