dnsapi: dns_ns_name_pton() is unused so remove it.

[Francois Gouget]

---

dns_ns_name_pton() has been unused since the following commit removed a 
bunch of other unused functions that were causing trouble:

   commit d1a3383d531664af984c5245c5916228322653f2
   Author: Alexandre Julliard <julliard at winehq.org>

       dnsapi: Remove a bunch of unused functions that cause naming 
       conflicts.
