x86: Use "do { } while(0)" for empty lock_cmos()/unlock_cmos() macros
gcc noticed (when using -Wempty-body) that our use of lock_cmos() and unlock_cmos() in arch/x86/include/asm/mach_traps.h is potentially problematic : arch/x86/include/asm/mach_traps.h:32:15: warning: suggest braces around empty body in an ¡else¢ statement [-Wempty-body] arch/x86/include/asm/mach_traps.h:40:16: warning: suggest braces around empty body in an ¡else¢ statement [-Wempty-body] Let's just use the standard 'do {} while (0)' solution. That shuts up gcc and also prevents future problems if the macros should end up being used in a similar situation elsewhere.
