Description of problem:
When addNode() failed in addNodeAnnotations(), the node's IPAM can be
overwritten by subsequent addNode() retry attempts. As the result, the
same IP can be allocated to multiple pods.
retryPod worker is started too soon, which could start to handle add Pod
request and allocate duplicate Pod IPs before IPs of the existing Pods are
reserved in syncPods().
Version-Release number of selected component (if applicable):
Steps to Reproduce:
No duplicate IPs
Fixed in upstream PR: https://github.com/ovn-org/ovn-kubernetes/pull/2928
