Describe the bug

Please refer to https://github.com/sgl-project/sglang/actions/runs/19047100376/job/54399299632?pr=10044 for more details

It's very likely because the latest changes in sgl-kernel for kvcacheio does not take AMD's code path into account.

Reproduction

python3 -m sglang.launch_server --model-path meta-llama/Llama-3.1-8B-Instruct --enable-hierarchical-cache --mem-fraction-static 0.7 --hicache-size 200 --device cuda --host 127.0.0.1 --port 11000
