[PATCH 2/3] um: elf.h: fix W=1 warning for empty body in 'do' statement

[Randy Dunlap]

Use the common kernel style to eliminate a warning:

./arch/x86/um/asm/elf.h:215:32: warning: suggest braces around empty body in ‘do’ statement [-Wempty-body]
 #define SET_PERSONALITY(ex) do ; while(0)
                                ^
