Description of problem:
OCP 4.11: nmstate-operator installed cluster on POWER shows issues while adding new dhcp interface. 

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

[root@rdr-shw-nm-3c3f-bastion-0 ~]# oc version
Client Version: 4.11.0-0.nightly-ppc64le-2022-05-04-095738
Kustomize Version: v4.5.4
Server Version: 4.11.0-0.nightly-ppc64le-2022-05-04-095738
Kubernetes Version: v1.23.3+d464c70

Nmstate Operator Version:  kubernetes-nmstate-operator.4.11.0-202205020057


How reproducible: Always


Steps to Reproduce:
1. Deploy kubernetes-nmstate-operator
2. Create an interface on nodes in the cluster by applying a NodeNetworkConfigurationPolicy

cat dhcp-nncp.yaml
apiVersion: nmstate.io/v1
kind: NodeNetworkConfigurationPolicy
metadata:
  name: env33
spec:
  nodeSelector:
    kubernetes.io/hostname: worker-0
  desiredState:
    interfaces:
    - name: env33
      description: dhcp routing on env33
      type: ethernet
      state: up
      ipv4:
        dhcp: true
        enabled: true

# oc apply -f dhcp-nncp.yaml
nodenetworkconfigurationpolicy.nmstate.io/env33 configured


Actual results:
[root@rdr-shw-nm-3c3f-bastion-0 ~]# oc get nncp
NAME    STATUS
env33   Degraded

Expected results:
[root@rdr-shw-nm-3c3f-bastion-0 ~]# oc get nncp
NAME    STATUS
env33   Available
