net: force a list_del() in unregister_netdevice_many()
unregister_netdevice_many() API is error prone and we had too
many bugs because of dangling LIST_HEAD on stacks.
See commit f87e6f47933e3e ("net: dont leave active on stack LIST_HEAD")
In fact, instead of making sure no caller leaves an active list_head,
just force a list_del() in the callee. No one seems to need to access
the list after unregister_netdevice_many()
