codecparsers: h264: fix parsing of slice groups for map type = 2.
When parsing slice groups information for slice_group_map_type = 2, we should only be reading up to num_slice_groups_minus1 groups since there is always a "leftover" slice group and as many "foreground" slice groups as needed. This fixes parsing for SVCBMT-5 and SVCBMT-12 whereby the base layer would have incorrectly been parsed to have up to 38 reference frames in list0, which is not possible.
