Andreas Rheinhardt 6e8fcd9c56 avcodec/mpeg12: Don't initialize encoder-only parts of RLTable ...

ff_mpeg12_init_vlcs() currently initializes index_run, max_level and
max_run of ff_rl_mpeg1/2; yet the only user of these fields is the
MPEG-1/2 encoder which already initializes these tables on its own.
So remove the initializations in ff_mpeg12_init_vlcs(); this also
simplifies making ff_mpeg12_init_vlcs() thread-safe.
