kernel: fix to follow the implied_bounds_entailment

[alexandruradovici]

Pull Request Overview

This pull request (hopefully) fixes the implied impl bounds. It updates the ListNode impl for MLFQProcessNode and Deref impl for StaticRef following this rust compiler update. Without this fix, Tock cannot be built on newer Rust versions.

Testing Strategy

Tock builds now, I think it should be right.

TODO or Help Wanted

Feedback from someone understanding better the lifetime definitions would be great.

Documentation Updated

• Updated the relevant files in /docs, or no updates are required.

Formatting

• Ran make prepush.

I saw your PRs now 😃

I am closing this in favor of Brad's PRs since I think the StaticRef example is qualitatively different than the MLFQ change (which was basically just a typo) and because those PRs have already gotten reviews
