[Hardware][Gaudi][Bugfix] Fix error for guided decoding

[zhouyu5]

It fixes the error on Gaudi when enabling guided decoding:

RuntimeError: synNodeCreateWithId failed for node: strided_insert with synStatus 1 [Invalid argument]

After fix, all UT have passed for guided decoding and tool calling, including:

vllm-fork/tests/entrypoints/llm/test_guided_generate.py
vllm-fork/tests/tool_use/*.py

👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can do one of these:

• Add ready label to the PR
• Enable auto-merge.

🚀

Could we simply use scores = scores.add(mask) for all cases? I am not familiar with performance differences between this and scores.add_(mask)
