fib_frontend: fix possible NULL pointer dereference
[ Upstream commit a0065f266a9b5d51575535a25c15ccbeed9a9966 ]
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.
