Bug description:
  = Original bug description =

  In OpenStack version Victoria, neutron-ovn-db-sync generates insufficient flow for port no security-group or disable port-security.
  ---> As a result, the port is not connected to the network.

  = Ubuntu SRU details =

  [Impact]
  The neutron-ovn-db-sync tool is used to syncing neutron networks and ports with OVN databases. When the tool is run, ports with port security disabled are incorrectly being added to the drop port group causing all traffic to be dropped by default.

  [Test Case]
  - Create a VM
  - Disable port security
  - Remove NB & SB DB
  - Run command neutron-ovn-db-sync-util to resync from neutron to NB database
  neutron-ovn-db-sync-util --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --ovn-neutron_sync_mode repair
  - Restart ovn-controller
  - VM with port disable security die without the fix

  [Regression Potential]
  This is a simple patch that fixes the logic of an if statement. This has been fixed in the victoria+ Ubuntu package versions since 2022-01-12, and has been fixed in the upstream stable/ussuri branch since 2021-11-11.
