Title:
  Execute neutron-ovn-db-sync-util  report TypeError

Status in neutron:
  Fix Released

Bug description:
  A TypeError was thrown during a synchronization command(eutron-ovn-db-sync-util) execution. By checking the error call stack, it was found that it was an error during the creation of QoS. After analysis, there should be a port in the Neutron database, but not in the ovn-nb database. At this time, when executing the UpdateLSwitchQosOptionsCommand to create a logical port and update the QoS, it was found that the port_id is None. tracking variable  port_id is obtained by executing AddLSwitchPortCommand. It should be that this command did not set the port_id correctly caused. Analyzing AddLSwitchPortCommand, it was found that if the port already exists, no result was set. 
  This seems a bit contradictory. It was determined earlier that the port does not exist, but later it does. I think this situation may occur when executing synchronization commands and calling the API that creates the port. This operation is not very reasonable.

  But I think the AddLSwitchPortCommand command should return consistent
  results. This issue should be fixed.
