SRU Justification:
[Impact]
A race condition can occur that can be triggered when cleaning up LXC
containers that use NAT/netns.

[Fix]
commit 945b2b2d259d1a4364a2799e80e8ff32f8c6ee6f

[Testcase]
Using many LXC containers with NAT/netns and creating and destroying may
trigger this issue.

FYI, this is already in utopic/master-next.
