[https://nvbugs/6305404][chore] Unwaive DeepSeek V3 Lite L0 test

[Mgluhovskoi]

Description

Remove the remaining waiver for NVBug 6305404:

accuracy/test_llm_api_pytorch.py::TestDeepSeekV3Lite::test_bfloat16[mtp_nextn=0-attention_dp=True-cuda_graph=False-overlap_scheduler=False-torch_compile=True-enable_chunked_prefill=False-v2_kv_cache=True]

The original failure reported an mpi4py _manager_spawn thread surviving test teardown. A review of the surviving dependency-upgrade CI reports did not find the same thread-leak signature in multiple runs. The overlapping stale piecewise CUDA Graph teardown issue was fixed by commit 211482b36ac94820465df1791e5e1bc20d61624e.

Unwaiving the test restores L0 coverage and lets current main determine whether any residual failure remains.

Dev Engineer Review

• Updated tests/integration/test_lists/waives.txt to remove the mtp_nextn=0 waiver and add the corresponding mtp_nextn=2 waiver for DeepSeek V3 Lite bfloat16.
• Change is limited in scope and preserves the existing test path, SKIP format, and NVBug reference.
• No public API or code changes.

QA Engineer Review

• No test-db/ or qa/ files were modified; only the waiver list changed.
• The mtp_nextn=0 entry was removed and the mtp_nextn=2 entry was added.
• Given the mixed CI results and unavailable definitive CBTS coverage data, verdict: needs follow-up.
