Jesper Juhl 2ac13462b6 x86: Use "do { } while(0)" for empty flush_tlb_fix_spurious_fault() macro
If one builds the kernel with -Wempty-body one gets this
warning:

  mm/memory.c:3432:46: warning: suggest braces around empty body in an ¡if¢ statement [-Wempty-body]

due to the fact that 'flush_tlb_fix_spurious_fault' is a macro
that can sometimes be defined to nothing.
