    Filter HA router without HA port bindings after race conditions
    
    Neutron server will not be able to sync ha router data after
    race happened between get_ha_router_port_bindings and HA router
    deleting API call. Once the ports of L3HARouterAgentPortBinding
    were deleted the _process_sync_ha_data may get a None binding
    port, and then the _process_sync_ha_data will fail to get the
    HA interface port info due to the None port. This patch will
    filter the bindings without port.
