[https://nvbugs/6652876][fix] Fix release checks and waive Laguna XS FP8

[chzblych]

Description

This PR addresses two CI issues:

• Remove an unused LoraConfig import left by the LoRA refactor. The autoflake hook removes this import and causes release checks to fail.
• Waive accuracy/test_llm_api_pytorch.py::TestLagunaXS::test_fp8 only on RTXPro6000D, tracked by NVBug 6652876, due to a CUDA illegal memory access that can leave pytest hanging.

The waiver is hardware-scoped, so the test remains active on other platforms. These changes have no functional or public API impact.

Test Coverage

• pre-commit run autoflake --all-files --show-diff-on-failure --verbose
• Pre-commit hooks for the commit range from main to this branch
• Pre-commit hooks for tests/integration/test_lists/waives.txt, including formatting, duplicate-waive, and AST validation
• git diff --check

PR Checklist

• PR description explains both changes and their impact.
• Change follows the TensorRT-LLM coding guidelines.
• The test waiver is scoped to RTXPro6000D and linked to NVBug 6652876.
• No new code path, dependency, public API, ownership, documentation, or architecture change is introduced.
• The applicable checklist items have been reviewed.

Dev Engineer Review

• Removed the unused LoraConfig import from tests/unittest/llmapi/lora_test_utils.py.
• Added a waiver for TestLagunaXS::test_fp8 on RTXPro6000D in tests/integration/test_lists/waives.txt.
• The waiver references NVBug 6652876.
• The changes are correctly scoped and have no public API impact.
• Reported checks passed: autoflake, pre-commit hooks, and git diff --check.

QA Engineer Review

• No test functions were added, modified, or removed.
• No test-db/ or qa/ files were modified.
• The waiver entry uses the reported test, platform, and bug reference.
• Verdict: needs follow-up because CBTS coverage data is unavailable.
