ipvsadm: fix compile warning in print_largenum

ipvsadm.c: In function ‘print_largenum’:
ipvsadm.c:1445:3: warning: field width specifier ‘*’ expects argument of
 type ‘int’, but argument 2 has type ‘size_t’ [-Wformat=]
   printf("%*llu", len <= 8 ? 9 : len + 1, i);
   ^

Fix by reducing the scope and use int for len instead.
