[ Upstream commit 84be69b869a5a496a6cfde9b3c29509207a1f1fa ]

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.

Fixes: 430a049190de ("nexthop: Add support for nexthop groups")
