    l2 pop: check for more than 1 first active port on a node

    With high concurrency more than 1 port may be activated on an
    OVS agent at the same time (like VM port + a DVR port),
    so the patch mitigates the condition by checking for 1 or 2
    first active ports.

    Given that the condition also contains "or self.agent_restarted(context)"
    which makes it True first 180 sec (by default) after agent restart,
    I believe the downside of changing 1 to 2 should be negligible.

    Please see bug for more details on the issue.
