avcodec/mpeg4videodec: Remove always-true checks

codec_id is always AV_CODEC_ID_MPEG4 for mpeg4_decode_mb(),
as the MPEG-4 decoder is the only decoder for which
ff_mpeg4_decode_picture_header() as well as decode_init()
are ever called and these are the only places where
the decode_mb function pointer is ever set to mpeg4_decode_mb().
ff_mpeg4_workaround_bugs() is also only called for the MPEG-4
decoder (the caller checks the codec id).

(ff_mpeg4_decode_picture_header() is also called for the MPEG-4
parser, but it never uses the decode_mb function pointer.)
