net: use batched device unregister in veth and macvlan
veth devices dont use the batched device unregisters yet. Since veth are a pair of devices, it makes sense to use a batch of two unregisters, this roughly divides dismantle time by two. Fix this by changing dellink() callers to always provide a non NULL head. (Idea from Michał Mirosław) This patch also handles macvlan case : We now dismantle all macvlans on top of a lower dev at once.
