feat: remove patch terminating status for nodeclaim for adapting new nodeclaim crd changes

[rambohe-ch]

• Background:
  Because in latest NodeClaim CRD, spec.NodeClassRef.Group field is not allowed to empty. Then old nodeclaim that created by Kaito(before 0.6.0) can not be deleted by gpu-provisioner. the error as follows:

{"level":"INFO","time":"2025-10-17T15:49:18.350Z","logger":"controller","message":"ensure terminated nodeclaim","controller":"node.termination","controllerGroup":"","controllerKind":"Node","Node":{"name":"aks-ws1f323dc0c-28697582-vmss000000"},"namespace":"","name":"aks-ws1f323dc0c-28697582-vmss000000","reconcileID":"d35356ca-bc33-4bf2-b6b4-11ad2c9c66d3","nodeclaim":"ws1f323dc0c","isInstanceTerminated":false,"error":"NodeClaim.karpenter.sh \"ws1f323dc0c\" is invalid: spec.nodeClassRef.group: Invalid value: \"string\": group may not be empty"}

• Solution:
  The nodeclaim removal is blocked by patch terminating status for nodeclaim, so we comment these routine and make sure gpu-provisioner can delete old NodeClaim.
