autofs: move inclusion of linux/limits.h to uapi

linux/limits.h should be included by uapi instead of linux/auto_fs.h
so as not to cause compile error in userspace.

 # cat << EOF > ./test1.c
 > #include <stdio.h>
 > #include <linux/auto_fs.h>
 > int main(void) {
 >     return 0;
 > }
 > EOF
 # gcc -Wall -g ./test1.c
 In file included from ./test1.c:2:0:
 /usr/include/linux/auto_fs.h:54:12: error: 'NAME_MAX' undeclared here (not in a function)
   char name[NAME_MAX+1];
             ^
