🐛 Describe the bug
pytest -v -x v1/kv_connector/unit/test_nixl_connector.py::test_prompt_less_than_block_size was failed (#18490). #18429 wanted to fix it by skipping adding this request into the connector's metadata.
But the failure reason is the unit test has not been updated to due the changes in NixlConnectorSheduler.
The short (promot < block_size) do_remote_prefill request should be copied into the connector's metadata with an empty local_block_ids, so that NixlConnectorWorker can skip (async) reading remote kv blocks, but still be able to send notificaiton to the prefill worker to release its remote kv blocks.
