After Kuryr -> OVNKubernetes migration, few openshift/conformance/parallel tests failing.

Reproduced with both OCP 4.13/4.14 on top of OSP 16.2/17.1

Five times out of five attempts

1.Install OSP 16.2/17.1
2.Install OCP 4.13/4.14 cluster
3.Run Kuryr migration. [0]
4. Run https://github.com/openshift/origin openshift/conformance/parallel tests:
```
./openshift-tests run openshift/conformance/parallel --provider '{"type":"openstack"}' --file <name-of-input-file> --max-parallel-tests 10 --output-file <name-of-output-file>
```

Some tests are failing. (~35 failed tests out of 1319)

All tests are passing

- We noticed during the conformance run, that one of the worker nodes swapping between ready and not ready state
- Running the failed tests individually, they pass
- We can't observe this issue on a regular OVN-K installation (without the migration)
