mxf: memory leak with fuzzed file

Description

I found a memory leak in mpv with a fuzzed file. The problem appears to be in ffmpeg so I report it here directly.
Adding several fuzzed files like these to mpvs playlist will deplete my 16G of ram.

$ valgrind -v --tool=memcheck --leak-check=full ~/repository/mpv-build_vanilla_debug/ffmpeg_build/ffmpeg -loglevel 99 -i mxf_leak1.mxf
