gpu: nvgpu: POSIX MISRA cleanups in bug.h

Browse Source 
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.
