Subject: [PATCH] avcodec/aom_film_grain: Cast const away to suppress compiler
 warning

av_frame_side_data_add() typically takes ownership of
the provided AVBufferRef reference and therefore
uses a parameter of type AVBufferRef**; yet with
the AV_FRAME_SIDE_DATA_FLAG_NEW_REF, it creates
new references instead, without touching the given
reference. Therefore it is safe to cast const away.
