Fix coding guideline MISRA C:2012 Rule 14.4 in include/zephyr:

The controlling expression of an if statement
and the controlling expression of an iteration-statement shall have
essentially Boolean type.

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:

MISRA C:2012 Rule 14.4 (The controlling expression of an if statement
and the controlling expression of an iteration-statement shall have
essentially Boolean type.)

Use comparisons with NULL instead of implicitly testing pointers.
Use `do { ... } while (false)' instead of `do { ... } while (0)'.
Use comparisons with zero instead of implicitly testing integers.
