    [OVN] Only account for bound ports in metadata agent

    Due to bug #1922934 there might be situations with stale ports
    in the OVN database. When instances request metadata, the agent
    will try to fetch all ports for that particular network with the
    same IP address and there should be only one.

    However, when there are stale ports in OVN database but not in
    Neutron, those ports may have the same IP address and the result
    is that metadata won't work. As the stale ports will never be
    bound to any hypervisor, this patch is accounting only for
    bound ports so that those ports don't interfere until they
    eventually get fixed by the maintenance task.
