net: Fix more stale on-stack list_head objects.
From: Eric W. Biederman <ebiederm@xmission.com>
In the beginning with batching unreg_list was a list that was used only
once in the lifetime of a network device (I think). Now we have calls
using the unreg_list that can happen multiple times in the life of a
network device like dev_deactivate and dev_close that are also using the
unreg_list. In addition in unregister_netdevice_queue we also do a
list_move because for devices like veth pairs it is possible that
unregister_netdevice_queue will be called multiple times.
So I think the change below to fix dev_deactivate which Eric D. missed
will fix this problem. Now to go test that.
