include: kernel: added missing parenthesis

[tychofrei02]

Added missing parentheses around macro argument expansion.

This corresponds to following coding guideline:

Expressions resulting from the expansion of macro parameters shall be enclosed in parentheses

This PR is part of the enhancement issue #48002 which port the coding guideline fixes done by BUGSENG on the https://github.com/zephyrproject-rtos/zephyr/tree/v2.7-auditable-branch back to main

The commit in this PR is a subset of the original auditable-branch commit:

Some nitpicks where the rule is being overbroadly interpreted. I do worry about the tool you're using to detect this stuff if it's flagging constructs like this?

You are right. Those changes are unnecessary. I removed them.
