[Bug] CUDA runtime error: an illegal memory access was encountered when 8bit kv quant was enabled

### Checklist

### Describe the bug

I used this code to start a openAI server, it loaded successfully, but when I tried to generate some texts, it first output some texts and than raised a error "an illegal memory access was encountered"

this is the output↓

I looked on other issues, and I tried to set use_context_fmha=0 and to cache-max-entry-count to 0.1,neither of them worked, the only way I can solve it is to set quant-policy to 0 than it can run successfully.

I really want to use 8bit kv, is there somebody who can help me?

### Reproduction

```bash
#!/bin/bash
export CUDA_VISIBLE_DEVICES=1,2,3,4
source /usr/local/anaconda3/bin/activate /home/aabbccddwasd/.conda/envs/obj013-env-lmdeploy
lmdeploy serve api_server ../obj013-qwen/Qwen1.5-110B-Chat-AWQ-turbomind \
--server-name 0.0.0.0 \
--server-port 8000 \
--tp 4 \
--model-format awq \
--quant-policy 8 \
--cache-max-entry-count 0.55
```
