um: pgtable.h: Fix W=1 warning for empty body in 'do' statement
Use the common kernel style to eliminate a warning:
./arch/um/include/asm/pgtable.h:305:47: warning: suggest braces around empty body in ‘do’ statement [-Wempty-body]
#define update_mmu_cache(vma,address,ptep) do ; while (0)
^
mm/filemap.c:3212:3: note: in expansion of macro ‘update_mmu_cache’
update_mmu_cache(vma, addr, vmf->pte);
