avcodec/mpeg12dec: Don't call ff_mpeg12_common_init() It only sets [yc]_dc_scale_table and these tables are only read in ff_set_qscale(); but the MPEG-1/2 decoders don't call ff_set_qscale() at all. (Furthermore, given that intra_dc_precision is always zero for a decoder at this point, ff_mpeg12_common_init() actually set these pointers to what ff_mpv_common_defaults() already set them.)
