[FFmpeg-devel] [PATCH v3 4/5] avcodec/mmaldec: Avoid creating unnecessary reference, simplify code

ffmal_add_packet() basically duplicated the logic in
av_packet_make_refcounted() with the added twist that it always
created a reference even if one is already available.
This commit stops doing this.
