Currently, IPv4 routes are flushed in ->exit_batch() after all devices are unregistered. Unlike IPv6, IPv4 routes are not added from the fast path, so we can flush routes before default_device_exit_batch(). Let's call ip_fib_net_exit() from ->exit_rtnl() to save one RTNL locking dance. ip_fib_net_exit() must use list_del_rcu() for fib_table for the fast path on dying dev.
