xfrm interface: fix management of phydev
With the current implementation, phydev cannot be removed: $ ip link add dummy type dummy $ ip link add xfrm1 type xfrm dev dummy if_id 1 $ ip l d dummy kernel:[77938.465445] unregister_netdevice: waiting for dummy to become free. Usage count = 1 Manage it like in ip tunnels, ie just keep the ifindex. Not that the side effect, is that the phydev is now optional.
