Users can pass the DNS information throught "nameserver=" cmdline,
there maybe duplicated inputs.
"/etc/resolv.conf" have some restrictions on the number of DNS items
effective, so make sure that this file contains no duplicated items.
We achieve this by simply making the file have no duplicated lines.
