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.
