My first bug fix landed in vLLM

My first bug fix just landed in vLLM 😁

We hit the bug running prefill/decode disaggregation with NVIDIA Dynamo in production, and fixed it upstream: vllm-project/vllm#57734.

vLLM is one of the most widely used open-source engines for serving LLMs, with more than 93,000 stars on GitHub.

Thanks Nicolò Lucchesi for the review.
