net: ipv4: Do not drop to make_route if oif is l3mdev
Commit e0d56fdd7342 was a bit aggressive removing l3mdev calls in
the IPv4 stack. If the fib_lookup fails we do not want to drop to
make_route if the oif is an l3mdev device.
Also reverts 19664c6a0009 ("net: l3mdev: Remove netif_index_is_l3_master")
which removed netif_index_is_l3_master.
Fixes: e0d56fdd7342 ("net: l3mdev: remove redundant calls")
