fib_frontend: fix possible NULL pointer dereference
The two commits 0115e8e30d (net: remove delay at device dismantle) and 748e2d9396a (net: reinstate rtnl in call_netdevice_notifiers()) silently removed a NULL pointer check for in_dev since Linux 3.7. This patch re-introduces this check as it causes crashing the kernel when setting small mtu values on non-ip capable netdevices.
