How reproducible:


Steps to Reproduce:
1.1.Create a mhc on osp platform 
apiVersion: machine.openshift.io/v1beta1
kind: MachineHealthCheck
metadata:
  name: example
  namespace: openshift-machine-api
spec:
  selector:
    matchLabels:
      machine.openshift.io/cluster-api-cluster: <your cluster name>
      machine.openshift.io/cluster-api-machine-role: worker
      machine.openshift.io/cluster-api-machine-type: worker
      machine.openshift.io/cluster-api-machineset: <Your machineset name>
  unhealthyConditions:
    - type: Ready
      status: Unknown
      timeout: 300s
    - type: Ready
      status: 'False'
      timeout: 300s
  maxUnhealthy: 3
  
  Expected Result
  
  mhc should get created successfully
  
2.run oc get mhc

Actual result :
 MAXUNHEALTHY   EXPECTEDMACHINES   CURRENTHEALTHY
<your mhc>   3              0                  0 

Expected :
Expected and Current healthy should be shown as per cluster and should not be 0 


Additional info:
For more info Run oc get mhc <Your machine healthcheck> -o yaml

and get mhc controller log by running :

oc log <Machine controller Pod> -c machine-healthcheck-controller
