avcodec/mpeg12enc: Also inline chroma subsampling
ff_mpeg1_encode_mb() contains two inlined calls to mpeg1_encode_mb_internal(); these calls are supposed to inline the properties depending upon the color space used. Yet inlining vertical chroma subsampling (which allows to remove complete branches and blocks depending upon them) has been forgotten.
