Timeout with multiple AMD GPUs tensor parallelism in vLLM
## Problem Description

When attempting to run Optimum Benchmark in vLLM using tensor parallelism across multiple AMD GPUs (MI210), I encounter a timeout error from NCCL watchdog. However, the benchmark works fine with a single AMD GPU in vLLM, and the vLLM API server functions correctly when using tensor parallelism.
During the benchmark the VRAM% and GPU usage % from rocm-smi were 90-100%.

## Environment

- GPUs: AMD MI210 (x4)
- ROCm version: 6.1.2
- Framework: vLLM (tried 0.4.3 and 0.5.3)
- Optimum Benchmark version: 0.4.0

## Tested Configurations

1. Multi-GPU setup (failing)
2. Single-GPU setup (working)
3. API Server Inference with Tensor Parallelism [(from ROCm Documentation)](https://rocm.docs.amd.com/en/docs-6.2.0/how-to/llm-fine-tuning-optimization/llm-inference-frameworks.html#vllm-inference) (working)

## Docker Images Tested

1. Official vLLM docker for ROCm: [Dockerfile.rocm](https://github.com/vllm-project/vllm/blob/main/Dockerfile.rocm)
2. ROCm's fork of vLLM: [Dockerfile.rocm](https://github.com/ROCm/vllm/blob/main/Dockerfile.rocm)

Both Docker images resulted in the same issue with Optimum Benchmark on multiple GPUs.
