### What this PR does / why we need it?
Now, from https://github.com/vllm-project/vllm-ascend/pull/3967, chunked
prefill and spiltfuse are defaultly enabled.
The e2e test for mtp breaks now.
After locating the bug, we found that a triton operator does not support
chunked prefill.
But if let e2e test be skipped is bad.
So, we changed the e2e test to only test the case in which chunked
prefill is off.
### Does this PR introduce _any_ user-facing change?
N/A
### How was this patch tested?
Because we only modified
`test_models_distributed_Qwen3_NEXT_MTP_TP4_SIMILARITY`.
So, we only run `pytest -s
tests/e2e/multicard/test_qwen3_next.py::test_models_distributed_Qwen3_NEXT_MTP_TP4_SIMILARITY`
locally to test it.
Below is the result:
