Kuniyuki Iwashima 3671f0419d mpls: Set rt->rt_nhn just before returning from mpls_nh_build_multi(). ... Commit f0914b8436 ("mpls: Hold dev refcnt for mpls_nh.") added change_nexthops() loop to call netdev_put() for the nexthop devices before freeing mpls_route. Then, mpls_nh_build_multi() was also changed to avoid iterating uninitialised nexthops in mpls_rt_free_rcu(). However, setting rt->rt_nhn to 0 at the entry of mpls_nh_build_multi() makes the following change_nexthops() no-op. Let's set rt->rt_nhn just before returning from mpls_nh_build_multi(). Fixes: f0914b8436 ("mpls: Hold dev refcnt for mpls_nh.")
