fix KarrasVePipeline bug

[junhsss]

KarrasVePipeline crashes when output_type="pil"

        sample = (sample / 2 + 0.5).clamp(0, 1)
        image = sample.cpu().permute(0, 2, 3, 1).numpy()
        if output_type == "pil":
            image = self.numpy_to_pil(sample)

should be

        sample = (sample / 2 + 0.5).clamp(0, 1)
        image = sample.cpu().permute(0, 2, 3, 1).numpy()
        if output_type == "pil":
            image = self.numpy_to_pil(image)
