Bug description:
This is a "continuation" of bug 1403152, as that bug has been marked
"fix released" and recent reports of failure may (or may not) be a new
bug. Any further reports of the problem should please be reported
here instead of that bug.

[Impact]
When shutting down and starting containers the container network
namespace may experience a dst reference counting leak which results
in this message repeated in the logs:
unregister_netdevice: waiting for lo to become free. Usage count =
1
This can cause issues when trying to create net network namespace and
thus block a user from creating new containers.
[Test Case]
See comment 16, reproducer provided at https://github.com/fho/docker-
samba-loop
