[FFmpeg-devel] MAX_THREADS for ffmpeg-mt mp4

Attached as a separate patch for just libavcodec/h264.c

The other formats that use MAX_THREADS already had a check, so I
copied this from dnxhdenc.c
This prevents the crash, but is a fatal error:
[h264 @ 0x2873030]too many threads
[h264 @ 0x2873030]decode_slice_header error
