### What this PR does / why we need it? The `row_idx` parameter is no longer used since PR[#2689](https://github.com/vllm-project/vllm-ascend/pull/2689), so remove it across multiple files to remove unnecessary calculations and parameter passing. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? accuracy test passed for Qwen3 235B and DeepSeek V3 671B after this PR. - vLLM version: v0.11.0rc3 - vLLM main: https://github.com/vllm-project/vllm/commit/v0.11.0 --------- Signed-off-by: CaranLic <740821011@qq.com>
