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.)
