Rearranges Validate to match the functions within controller.go

if err := kController.Unmarshal(data); err != nil {
        return nil, nil, errors.Wrap(err, "unable to unmarshal data")
}

if err := kController.Validate(); err != nil {
        return nil, nil, errors.Wrap(err, "unable to validate data")
}

if err := kController.Fix(); err != nil {
        return nil, nil, errors.Wrap(err, "unable to fix data")
}

ros, extraResources, err := kController.Transform()
if err != nil {
        return nil, nil, errors.Wrap(err, "unable to transform data")
}
