The POSIX code does not need to be MISRA complient but any macro
code in the POSIX stuff does get checked by nature of the scanner.
Thus we get a lot of false positives that are annoying.
This change fixes a couple of issues in the BUG() and WARN()
macros: '__' prefixes, missing '{}' in if-conditions, and using
a non-boolean in boolean context.
