Bug description:

  [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
