avformat/mxfdec: disallow generic seek search If the demuxer does not provide per-stream indexes, the generic seek search can attempt to read the whole media file from the beginning when seeking. For large MXF files this can cause huge lockups for a seek after the last timestamp, which will eventually fail. So let's disable the generic seek for mxf, the demuxer's own seek code should handle seeking just fine.
