Code Review

This pull request improves a debug log message in vllm/model_executor/layers/fused_moe/deep_gemm_moe.py to correctly display the required alignment value. The change is correct and enhances the clarity of the log message for debugging purposes. Given that the change is minor and there are no high or critical severity issues, I have no specific review comments.
