Turn off data labels if data source is not the correct type
vtkPVRenderView::GetPieceProducer() could return a vtkDataObject, which is not an acceptable input type for vtkCellCenters nor vtkMaskPoints. When that happens, turn the visibility of the labels off to avoid a pipeline update, thereby avoiding an error message about invalid input.
