avcodec/vc1_parser: Don't call ff_vc1_init_common()

Browse Source 
It is unnecessary to initialize the VLCs: The only VLC
that was only ever used by the code reachable from the parser
was ff_vc1_bfraction_vlc; and this VLC has been removed.

Yet vc1dsp is still needed for startcode_find_candidate.
Maybe this should be factored out of vc1dsp in a later
commit.
