When we apply MOSC on cluster after MOSB is completed the MCP starts updating but the ReadyMachineCount is not properly updated

    Not frequent. Ablt to see in disconnected cluster 

    1.Apply MOSC
    2.Wait for MOSB to complete
    3.Check the MCP update

oc get mcp worker -w

Here able to see the in readymachinecount the count is moving from 0->1->0
Though later MCP is updated, but the update of machine is not happening properly

  MCP should be update like this 0->1->2->3
