Description of problem:
-----------------------
Update from 4.9.29 to 4.10.13 stuck and cluster's api unresponsive:

[kni@provisionhost-0-0 ~]$ oc get mcp
The connection to the server api.edge-0.qe.lab.redhat.com:6443 was refused - did you specify the right host or port?

[kni@provisionhost-0-0 ~]$ oc get nodes
The connection to the server api.edge-0.qe.lab.redhat.com:6443 was refused - did you specify the right host or port?

[kni@provisionhost-0-0 ~]$ oc get co
The connection to the server api.edge-0.qe.lab.redhat.com:6443 was refused - did you specify the right host or port?

After checking nodes via console found that IP addresses on 2 out of 3 nodes were on `bond0` interface as well as on `br-ex`:

Version-Release number of selected component (if applicable):
=============================================================
4.10.13


How reproducible:
=================
from time to time

Steps to Reproduce:
===================
1. Deploy baremetal IPI cluster with bonds configured on 'baremetal' network
2. Start OCP update


Actual results:
===============
Update stuck; wrong interfaces got IP addresses assigned


Expected results:
=================
Update succeeds; expected interfaces got IP addresses assigned

Additional info:
================
Virtual setup: 3 masters + 4 worker nodes
