[NETNS]: Fix loopback network namespace initialization.

The core patchset of the network namespace sent by
Eric Biederman does not do dynamic loopback creation.
So there is no call to alloc_netdev_mq which fills the
network namespace field of the netdevice.

This patch assign the loopback to the init network namespace.
