fix(asr): load VAD model on correct CUDA device
Previously, the VAD sub‐model was always initialized on the default CUDA device (cuda:0), even when a higher device_index was specified. This change sets `device_vad` to `cuda:{device_index}` whenever `device == 'cuda'`, while falling back to the original `device` string for non‐CUDA cases. This ensures the VAD model is loaded on the intended GPU.
