When decoding S picture, reference list with be force to set to only one left. Slot flag should be cleared for the already marked buffers at reference list. But decoded picture may not be correct if following AVS2 specification. So for S picture, keep those reference frames found by doi_of_ref and replace the content of the first reference frame with scene ref only.
