Don't delete br-ex on upgrade in multinode jobs

The hook for os-net-config in multinode NIC config templates contains
a call to `ovs-vsctl del-br br-ex` to remove the bridge we got from
nodepool and initialize network config. We need to avoid executing
that again on upgrade, or the Ansible process running the upgrade gets
stuck.
