Cherry-pick of https://github.com/ovn-org/ovn-kubernetes/pull/3063 from upstream. A missing comma before an "action=" meant that those OVS flows weren't getting added due to a parsing error. Second, the `k8s.ovn.org/node-gateway-router-lrp-ifaddr` annotation added by https://github.com/ovn-org/ovn-kubernetes/pull/2862 was only evaluated on node add, but we can't always rely on that. It might be added slightly later in an Update event.
The missing comma is a real problem for Windows hybrid clusters.
Downstream 4.12 merge PR merged which contains this fix.
