When using mpls over gre/gre6 setup, rt->rt_gw4 address is not set, the
same for rt->rt_gw_family. Therefore, when rt->rt_gw_family is checked
in mpls_xmit(), neigh_xmit() call is skipped. As a result, such setup
doesn't work anymore.
This issue was found with LTP mpls03 tests.
Fixes: 1550c171935d ("ipv4: Prepare rtable for IPv6 gateway")
