veth: Fix unregister_netdevice_queue for veth
I tested the recent unregister many changes and got a weird,
nasty and seemingly unrelasted kernel oops. Changing
unregister_netdevice_queue to use list_move_tail fixes
the problem for me.
ip link add type veth
rmmod veth
ls /sys/class/net/
showed one of the veth devices still present.
A subsequent ip link oopsed the box.
