NAR CR goes into BackingOff phase when associated backup is removed

[PrasadJoshi12]

Steps followed:-
Create Non Admin Backup
Created NonAdminRestore. (wait for restore to complete)

$ oc get nar -n test -o yaml
apiVersion: v1
items:
- apiVersion: oadp.openshift.io/v1alpha1
  kind: NonAdminRestore
  metadata:
    creationTimestamp: "2025-02-06T11:01:02Z"
    finalizers:
    - nonadminrestore.oadp.openshift.io/finalizer
    generation: 2
    name: test-nar
    namespace: test
    resourceVersion: "126191"
    uid: eceae35a-e6a9-4a95-855a-073c2c8132e8
  spec:
    restoreSpec:
      backupName: test
      hooks: {}
      itemOperationTimeout: 0s
  status:
    conditions:
    - lastTransitionTime: "2025-02-06T11:01:02Z"
      message: restore accepted
      reason: RestoreAccepted
      status: "True"
      type: Accepted
    - lastTransitionTime: "2025-02-06T11:01:02Z"
      message: Created Velero Restore object
      reason: RestoreScheduled
      status: "True"
      type: Queued
    phase: Created
    queueInfo:
      estimatedQueuePosition: 0
    veleroRestore:
      nacuuid: test-test-nar-465e530d-2de7-4598-94ca-4d85d9f3f892
      name: test-test-nar-465e530d-2de7-4598-94ca-4d85d9f3f892
      namespace: openshift-adp
      status:
        completionTimestamp: "2025-02-06T11:01:04Z"
        hookStatus: {}
        phase: Completed
        progress:
          itemsRestored: 15
          totalItems: 15
        startTimestamp: "2025-02-06T11:01:02Z"
        warnings: 4

3. Now delete NonAdminBackup CR by setting deleteBackup: true
4. Observe NAR CR

apiVersion: oadp.openshift.io/v1alpha1
  kind: NonAdminRestore
  metadata:
    creationTimestamp: "2025-02-06T11:01:02Z"
    finalizers:
    - nonadminrestore.oadp.openshift.io/finalizer
    generation: 2
    name: test-nar
    namespace: test
    resourceVersion: "126418"
    uid: eceae35a-e6a9-4a95-855a-073c2c8132e8
  spec:
    restoreSpec:
      backupName: test
      hooks: {}
      itemOperationTimeout: 0s
  status:
    conditions:
    - lastTransitionTime: "2025-02-06T11:01:46Z"
      message: 'NonAdminRestore spec.restoreSpec.backupName is invalid: NonAdminBackup
        is not ready to be restored'
      reason: InvalidRestoreSpec
      status: "False"
      type: Accepted
    - lastTransitionTime: "2025-02-06T11:01:02Z"
      message: Created Velero Restore object
      reason: RestoreScheduled
      status: "True"
      type: Queued
    phase: BackingOff
    queueInfo:
      estimatedQueuePosition: 0
    veleroRestore:
      nacuuid: test-test-nar-465e530d-2de7-4598-94ca-4d85d9f3f892
      name: test-test-nar-465e530d-2de7-4598-94ca-4d85d9f3f892
      namespace: openshift-adp
      status:
        completionTimestamp: "2025-02-06T11:01:04Z"
        hookStatus: {}
        phase: Completed
        progress:
          itemsRestored: 15
          totalItems: 15
        startTimestamp: "2025-02-06T11:01:02Z"
        warnings: 4

Actual Result:- NAR gets reconciled again which should not happen when velero restore is completed.

Expected Result:- There should be no errors on NAR CR
