avformat/mxfenc: Remove redundant DNXHD frame size checks

The actual frame_size is no longer used since commit
3d38e45eb85c7a2420cb48a9cd45625c28644b2e; and the check for
"< 0" is equivalent to the CID being valid. But this is already
checked by avpriv_dnxhd_get_interlaced() (and is actually already
ensured by mxf_dnxhd_codec_uls containing this CID).
