Fix a deadlock between child interface creation/deletion and ipoib start/stop. The former takes vlan_mutex, and then might take RTNL via register_netdev()/unregister_netdev(). The latter is executed with RTNL held, and tries to take vlan_mutex, which can lead to an AB-BA deadlock. Fix this by having the child interface creation/deletion code take the RTNL first so vlan_mutex always nests inside RTNL. We can use register_netdevice() for child interfaces because we form the interface name from the parent interface and hence don't need the '%' expansion of register_netdev().
