Describe the bug

When sglang is started with the --api-key parameter, an authentication error will be reported when using bench_serving test, even if the OPENAI_API_KEY environment variable is added.

Reproduction

1. Start sglang server with: --model /data/llms/Qwen2.5-7B-Instruct --served-model-name=model --tp 2 --enable-p2p-check --api-key kebe
2. Run bench serving OPENAI_API_KEY=kebe python3 -m sglang.bench_serving --backend sglang --dataset-name random --num-prompts 3000 --random-input 1024 --random-output 1024 --random-range-ratio 0.5 --tokenizer Qwen/Qwen2.5-7B-Instruct
