We will call ip_fib_net_exit() from ->exit_rtnl().
However, some paths will still access net->ipv4.fib_table_hash
after ->exit_rtnl().
For example, fib_flush() is called from fib_disable_ip() for
NETDEV_UNREGISTER.
Let's move kfree(net->ipv4.fib_table_hash) and fib4_notifier_exit()
from ip_fib_net_exit() to its caller.
