[BugFix] Stop silent failures on compressed-tensors parsing

[dsikka]

Summary

• compressed-tensors has been silently failing if there are any config parsing errors and just sets the input_activations to None in those cases, which results in downstream failures that hide the root problem
• PR updates to stop the silent failure and changes the condition on input_quant

👋 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.

🚀

@dsikka I think there is a real issue in the CI here https://buildkite.com/vllm/ci-aws/builds/9886#0192911e-1065-4a85-8a1b-75071e80f1de/193-715

@mgoin Yup, which is why we need the PR which adds compressed-tensors to land. The current utils is out-of-date. This PR is secondary to make future failures more visible/not hide the root cause (i.e the issue you tagged is the real issue, which was silent before this PR)
