codecparsers: vc1: fix VOPDQUANT parser for DQUANT == 2

Fix parsing of VOPDQUANT when DQUANT == 2. In particular, DQUANTFRM is not present in the bitstream in this case and it shall be derived to the default value of zero (7.1.1.31.1).

I plan to apply this patch to all gst-plugins-bad branches. Thanks.
