Andreas Rheinhardt 3cc685b7bc avcodec/mjpegdec: Fix leak in case of invalid external Huffman tables
When using external Huffman tables fails during init, the decoder
reverts back to using the default Huffman tables; and when doing so,
the current VLC tables leak because init_default_huffman_tables()
doesn't free them before overwriting them.
