1. have a service of type `ClusterIP` with `internalTrafficPolicy: Local`
2. update to `okd-4.13`
3. observe `ovnkube-node`'s crash with
```
    State:       Waiting
      Reason:    CrashLoopBackOff
    Last State:  Terminated
      Reason:    Error
      Message:   sbin/iptables -t mangle -C OVN-KUBE-ITP -p TCP -d <nil> --dport 110 -j MARK --set-xmark 0x1745ec --wait]: e
xit status 2: iptables v1.8.7 (nf_tables): host/network `<nil>' not found
```

This does make sense in a way, because there is no external IP that this could apply to.  It arguably should not crash though.

I don't know whether it's possible to create these services with 4.13, but they could be created with 4.12.

 Some more info in the downstream bug.
