drivers: Fix coding guidelines MISRAC:2012 Rule 14.4 do-whiles/Zero checks

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