mxfdemux: Sometimes seeks from the seeking thread in pull mode
Seeking demuxers in pull mode should happen in the demuxer sinkpad task thread, with mxfdemux it is generally the case, but then there are cases where it start pulling data from the seeking thread, for example in
validate.file.playback.seek_forward.op2b-mpeg2-wave_hd_mxf (only current -validate test where I saw that happen):
