[https://nvbugs/6541322][fix] Remove stale waiver for TestQwen3NextInstruct::test_bf16_4gpu[dep4]

[trtllm-agent]

Summary

• Root cause: The Qwen3-Next-80B bf16 TP4/EP4 test aborted during LLM startup on the V2 KV-cache Mamba SSM slot check, which computed only 75 available SSM slots against the 129 required by the configured batch size, raising before any model weights were loaded. The underlying defect was the V2 SSM pool being rounded below the minimum-slot floor implied by max_num_requests; that floor fix has since landed in HEAD via commit 7f7dccf, so the failing code path no longer exists. The waiver entry for this test therefore outlived the defect it was tracking.
• Fix: Verification on current HEAD confirmed the reported failure signature is gone — the run cleared init completely (weights loaded, 19 CUDA-graph sizes captured, KV cache sized, 3786 MMLU requests submitted), which is structurally incompatible with the reported abort that produced zero model-load lines. The only remaining crash was unrelated GPU co-tenancy (a peer process holding ~121 GB/GPU, visible only to in-container nvidia-smi, leaving 53 MB free at a cublas allocation), so no product change was warranted. The change is waiver-only: drop the dep4 SKIP line so the test runs again in CI, while leaving the sibling tp1_block_reuse-cutlass waiver under the same bug in place since it was not shown to be fixed.

Dev Engineer Review

• Removed the stale dep4 waiver for TestQwen3NextInstruct::test_bf16_4gpu[dep4].
• The waiver removal matches the fix for the V2 Mamba SSM slot-sizing defect.
• The sibling tp1_block_reuse-cutlass waiver remains unchanged.
• The test-list change is limited to one valid waiver entry.

QA Engineer Review

• Modified tests/integration/test_lists/waives.txt.
• Removed one waiver entry.
• No test code changed.
• CBTS coverage data is unavailable. Verdict: needs follow-up.
