While this patch make some unknown memory usage problem. To quick fix the problem, let's expend the `max_split_size_mb` to a larger value to avoid weight load oom issue. Further solution is to remove the patch and address weight loader v2 from vLLM. Closes: https://github.com/vllm-project/vllm-ascend/issues/3251 ### Does this PR introduce _any_ user-facing change?
