avcodec/vc1dec: Don't open and close decoder during init This is done since 16af29a7a6deff3f6081fca1e36ad96cf8fec77d (and is actually unnecessary, because the tables initialized in ff_msmpeg4_decode_init() are only ever used in vc1_block.c which is only entered after a call to ff_msmpeg4_decode_init()) in a very ugly manner; said manner had the byproduct of involving lots of unnecessary allocations and even opening and closing a hwaccel in case one is used. This commit achieves the aim of 16af29a7a6deff3f6081fca1e36ad96cf8fec77d by initializing the VLCs used by VC-1 in ff_vc1_init_common().
