[CI][Bugfix] Quickfix for DPMetaData (#3234)

### What this PR does / why we need it?
Fix `dpmetadata` and `Qwen3MoeSparseMoeBlock` break introduced by
26a7a33b88 (diff-c1550d0a38469d039370567d8981969530cbfffc7302cd1778e7c2c8a9322dea)

NOTE: we maintain a different sp in vllm-ascend with vllm, thus we can
just use `cu_tokens_across_sp(1)` as `cu_tokens_across_dp_cpu`
