### What this PR does / why we need it? After refactoring vllm_ascend/models and FusedMoE, we are unable to pass `gate` from deepseekv2.py to `AscendFusedMoE.forward`, which will result in error when running deepseek v3/r1 with allgather. Hence, this pr removes `gate` related computations from FusedMoE module in eager/aclgraph mode. ### Does this PR introduce _any_ user-facing change? `rm_router_logits` is deprecated in eager/aclgraph. ### How was this patch tested? e2e & ut - vLLM version: v0.11.0rc3 - vLLM main: https://github.com/vllm-project/vllm/commit/releases/v0.11.1 Signed-off-by: Pr0Wh1teGivee <calvin_zhu0210@outlook.com>
