      Description of problem:

      When a valid PinnedImageSet is applied, the PinnedImageSets reference in the MCN’s status displays a default `LastFailedGeneration` value of 0.

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

      4.19.0-0.nightly-arm64-2025-03-21-080021

      How reproducible:

      Always.

      Steps to Reproduce:

      1. Apply a valid PIS.

      apiVersion: machineconfiguration.openshift.io/v1alpha1
kind: PinnedImageSet
metadata:
  name: test-pinned
  labels:
    machineconfiguration.openshift.io/role: "worker"
spec:
  pinnedImages:
   - name: quay.io/openshift-release-dev/ocp-release@sha256:513cf1028aa1a021fa73d0601427a0fbcf6d212b88aaf9d76d4e4841a061e44e
   - name: quay.io/openshift-release-dev/ocp-release@sha256:61eae2d261e54d1b8a0e05f6b5326228b00468364563745eed88460af04f909b

      2. Wait for the PIS application to complete and view the MCN for a targeted node.

      $ oc describe machineconfignode/<node-name>

  Pinned Image Sets:
    Current Generation:      1
    Desired Generation:      1
    Last Failed Generation:  0
    Name:                    test-pinned

      Actual results:

      The PinnedImageSets reference contains a value for LastFailedGeneration.

      Expected results:

      Since no error has occurred, no LastFailedGeneration should be populated.

      Additional info:

      If testing in a cluster with an api version later than API PR #2201’s merge, both the `LastFailedGeneration` and `LastFailedGenerationError` fields are populated with default values on a successful PIS application. Example:

      Status:
  Pinned Image Sets:
    Current Generation:            1
    Desired Generation:            1
    Last Failed Generation:        0
    Last Failed Generation Error: 
    Name:                          test-pinned
