Andreas Rheinhardt 84ac35ecb8 avcodec/mjpegenc: Fix segfault when freeing incomplete context
When allocating the MJpegContext fails (or if the dimensions run afoul
of the 65500x65500 limit), an attempt to free a subbuffer of said
context leads to a segfault in ff_mjpeg_encode_close().
Seems to be a regression since 467d9e27e0cb2bf74f41dc832f2f8d191ba58ec9.
