Description of problem (please be detailed as possible and provide log
snippests):
Network fencing is not applied on a node which is down when 'node.kubernetes.io/out-of-service=nodeshutdown:NoExecute' label is applied

Version of all relevant components (if applicable):
OCP 4.15 and ODF 4.15.0-126

bug (1 - very simple, 5 - very complex)?
1

Can this issue reproducible?
Yes

Can this issue reproduce from the UI?
Yes

If this is a regression, please provide more details to justify this:
NA

Steps to Reproduce:
1. Install Openshift data foundation and deploy a app pod in same node as that of rook ceph operator pod
2. Shutdown the node on which CephFS RWO pod is deployed
3.Once the node is down, add taint
```oc taint nodes <node-name> node.kubernetes.io/out-of-service=nodeshutdown:NoExecute ```
Wait for some time(if the application pod and rook operator are on the same node wait for bit logger) then check the networkFence cr status

Actual results:
Network fence is not created if the node is down, But pod gets rescheduled on the new node immedietely

Expected results:
Network fence should be created when the node is down

Additional info:
When the node is up and working if you apply the taint 'oc adm taint nodes compute-1 node.kubernetes.io/out-of-service=nodeshutdown:NoExecute' Network fence would be created
