Description of problem:

Version-Release number of selected component (if applicable):

4.12.0-0.nightly-2022-08-15-150248

How reproducible:

Steps to Reproduce:
1. Label one node as egress node
2. Create egressIP object $ oc get egressip -o yaml

apiVersion: k8s.ovn.org/v1
  kind: EgressIP
  metadata:
    creationTimestamp: "2022-08-19T07:00:13Z"
    generation: 4
    name: egressip
    resourceVersion: "164963"
    uid: da91f9ce-71da-4003-ba4e-df7d7c0f23d0
  spec:
    egressIPs:
    - 192.168.12.246
    namespaceSelector:
      matchLabels:
        org: pm
  status:
    items:
    - egressIP: 192.168.12.246
      node: huirwang-0819a-ngdlt-worker-0  

3. Created a namespace and test pods in it. The test pods scaled to 10. added org=pm label to it.

4. Scale down CNO to 0
5. Delete ovnkube-master pods
6. Scaled test pods to 1
$ $ oc get pods -n eags6 -o wide
NAME            READY   STATUS    RESTARTS   AGE   IP            NODE                            NOMINATED NODE   READINESS GATES
test-rc-bd56x   1/1     Running   0          17m   10.131.0.18   huirwang-0819a-ngdlt-worker-0   <none>           <none>

$ oc get ns  eags6 --show-labels
NAME    STATUS   AGE   LABELS
eags6   Active   18m   kubernetes.io/metadata.name=eags6,org=pm,pod-security.kubernetes.io/enforce-version=v1.24,pod-security.kubernetes.io/enforce=restricted

7. Scale up CNO to 1
8. Check lr-policy-list and snat

Actual results:
No lr-policy-list for egressip but it had snat here sh-4.4#  ovn-nbctl lr-policy-list ovn_cluster_router
