`enable-expert-parallel` crashes with `VLLM_OFFLOAD_WEIGHTS_BEFORE_QUANT=0` and `sym_int4` autoquant

Early playing around with the new `intel/llm-scaler-vllm:0.14.0-b8.3` release is very promising for Qwen 3.6 on dual B60s, but I've had to take out `--enable-expert-parallel` from my configs. In the b8.1 release, it was giving me a significant load speedup for Qwen3.6 35B A3B models. I have not tested with b8.2 releases.

I'm attaching the vllm log, my `compose.yaml` (renamed with .txt so github will accept it) as well as the .env file referenced in the compose (again with altered file extension). The non-default vllm launch args are in the logfile.
