    Not process security group for none active ports

    We recently met an issue during VM live migration:
    1. nova starts live migration
    2. plug ports on new host
    3. neutron-ovs-agent starts to process the port,
       but the port is in 'added' and 'updated' set
       at the same time.
    4. because nova still not activate the destination
       port binding, so there is no local vlan for
       this port.
    Then, ovs-agent met errors:
    Error while processing VIF ports: OVSFWTagNotFound:
    Cannot get tag for port tap092f38ed-a7 from its other_config: {}

    This fix is to remove ports of the
    "binding_no_activated_devices" for ``setup_port_filters``.
