vxlan: Remove access to nexthop group struct
vxlan driver should be using helpers to access nexthop struct internals. Remove open check if whether nexthop is multipath in favor of the existing nexthop_is_multipath helper. Add a new helper, nexthop_has_v4, to cover the need to check has_v4 in a group.
