Code Review
This pull request addresses a CI failure in test_flashinfer_cutlass_mxfp4_mxfp8_fused_moe by ensuring that the dequantized reference weight tensors are moved to the correct CUDA device. The change is correct and resolves the device mismatch issue. I have provided suggestions to consolidate the tensor conversion and device placement calls for improved code clarity and efficiency.

What will happen if we don't add the to(device) here?
