Description of problem:

Scaling of worker node is not happening automatically it needs a manual intervention for GRUB selection. 

Version-Release number of the following components:

Tested version: registry.svc.ci.openshift.org/ipv6/release:4.3.0-0.nightly-2020-02-05-064223-ipv6.3  



How reproducible:

Deploy an Openshift IPI cluster in latest fork ipv6/release:4.3.0-0.nightly-2020-02-05-064223-ipv6.3 once the cluster is up 

```

oc get nodes
NAME                                         STATUS   ROLES    AGE   VERSION
master-0.kni7.cloud.lab.eng.bos.redhat.com   Ready    master   22h   v1.16.2
master-1.kni7.cloud.lab.eng.bos.redhat.com   Ready    master   22h   v1.16.2
master-2.kni7.cloud.lab.eng.bos.redhat.com   Ready    master   22h   v1.16.2
worker-0.kni7.cloud.lab.eng.bos.redhat.com   Ready    worker   25m   v1.16.2
worker-1.kni7.cloud.lab.eng.bos.redhat.com   Ready    worker   20h   v1.16.2
worker-2.kni7.cloud.lab.eng.bos.redhat.com   Ready    worker   21h   v1.16.2
```
 
Steps to Reproduce:
1. Deploy the cluster 
2. Use the link -> https://github.com/openshift-kni/baremetal-deploy/blob/master/install-steps.md#deploy-the-provisioner-node-as-a-worker-node-using-metal3 to provision the worker using the bmh 
3. The worker will not come up until you go to idrac and select the GRUB menu manually. 

Actual results:
Worker-0 should come up without any manual intervention


Expected results:
worker node should come up without any manual intervention.
