cni: ommiting errors for endpoint not found on DEL
cni: ommiting errors for endpoint not found on DEL

If kubernetes tried to delete an endpoint where cilium didn't create it,
kubelet would stay in a loop retrying to delete the pod due the error
returned by cilium. Thus, we ommit the endpoint not found error on DEL
operations.
