avformat/asfdec_o: Check size vs. offset in detect_unknown_subobject()
Fixes: signed integer overflow: 2314885530818453566 + 7503032301549264928 cannot be represented in type 'long'
Fixes: 26639/clusterfuzz-testcase-minimized-ffmpeg_dem_ASF_O_fuzzer-6024222100684800
Alternatively this could be ignored but then the end condition of the loop
would be hard to reach as avio_tell() is int64_t
