The 8.2.z kernel BZ for the conntrack issue is https://bugzilla.redhat.com/show_bug.cgi?id=1851003

In that BZ, we see that the issue is marked resolved + verified in `kernel-4.18.0-193.11.1.el8_2`

```
$ oc image info --output json $(oc adm release info -a ~/openshift-cluster-installs/all-the-pull-secrets.json --image-for=machine-os-content quay.io/openshift-release-dev/ocp-release:4.5.0-rc.7-x86_64) | jq .config.config.Labels.version
"45.82.202007062333-0"
```

Booting up the RHCOS 45.82.202007062333-0

                   Version: 45.82.202007062333-0 (2020-07-06T23:37:07Z)
[core@cosa-devsh ~]$ rpm -q kernel
kernel-4.18.0-193.12.1.el8_2.x86_64
```

A newer kernel is present than the one in the 8.2.z BZ, so marking this VERIFIED against 4.5.0-rc.7
