nexthop: Fix attribute checking for groups
For nexthop groups, attributes after NHA_GROUP_TYPE are invalid, but nh_check_attr_group starts checking at NHA_GROUP. The group type defaults to multipath and the NHA_GROUP_TYPE is currently optional so this has slipped through so far. Fix the attribute checking to handle support of new group types.
