David Ahern 0bc26d1ca3 net: ipv6: Compare lwstate in detecting duplicate nexthops ...

commit f06b7549b7 upstream.

Lennert reported a failure to add different mpls encaps in a multipath
route:

  $ ip -6 route add 1234::/16 \
        nexthop encap mpls 10 via fe80::1 dev ens3 \
        nexthop encap mpls 20 via fe80::1 dev ens3
  RTNETLINK answers: File exists

The problem is that the duplicate nexthop detection does not compare
lwtunnel configuration. Add it.

Fixes: 19e42e4515 ("ipv6: support for fib route lwtunnel encap attributes")
