csiaddons: allow deleting of the CR

The pod is set as the owner of the csiaddons
node object, and when the owner pod is deleted
the csiaddons need to be deleted as well, When
the delete Reconciles happens we cannot get the
pod deletails to resolve the endpoint and we dont
need that as well when we are deleting the CR.
