Title:
  Add and delete port test fails in the Debian package due to error
  logged from vif-plug-representor

Status in ovn package in Ubuntu:
  Fix Released
Status in ovn source package in Lunar:
  Fix Released

Bug description:
  OVN commit 264c825f0a0e ("ovn-controller: remove un-necessary "trying
  to release" warnings") added a test that fails if any warning or error
  is logged from the ovn-controller.

  This revealed the fact that the OVN-VIF representor plugin logs an error while running the test:
  ./ovn.at:35873: check_logs "" hv1

  942. ovn.at:35873: 942. Add and delete port -- ovn-northd -- parallelization=yes -- ovn_monitor_all=no (ovn.at:35873): FAILED (ovn.at:35873)

  From cursory view, I do not see this logged on an actual production
  setup with ovn-controller running directly on a host. I do see it when
  running this test in a container though.

  We should probably make the failure graceful at the initialization
  stage, and rather log warnings if this state is found while doing a
  lookup, or just lower the severity to INFO/DBG.
