[PATCH] remount: fs/jffs2

 - jff2->remount_fs() was buggy - it played with sb->s_flags instead of
   doing modifications to *flags (->s_flags will be overwritten using
   *flags right after the call of ->remount_fs()).  Moreover, it tried
   to do the wrong thing - it should just enforce noatime and be done
   with that.  Fixed, ACKed by maintainer.
