Description of problem:
When updating the tuningConfig of a NodePool to point to a different ConfigMap, the NodePool becomes stuck in the Updating state. The error indicates that more than one ConfigMap status is detected, even though the tuningConfig list references only a single ConfigMap. Additionally, stale status ConfigMaps remain for each NodePool that was updated. The issue resolves only after manually deleting the old ConfigMap.
Version-Release number of selected component (if applicable):
MCE version: 2.9 Hypershift operator Image: registry.redhat.io/multicluster-engine/hypershift-rhel9-operator@sha256:f8c3898e29f8c0a20c3be92bc4ee5a9443b9fc8218db95ba541fe3e57a89c40d
How reproducible:
always
Steps to Reproduce:
1. Create a NodePool and reference Performance Profile ConfigMap in the tuningConfig.
2. Update the NodePool to reference different ConfigMap instead.
3. Observe the NodePool status.
Actual results:

Expected results:
The nodepool should update and new config map configurations be applied on the Hosted cluster.
