[Samba] dhcp-dyndns.sh creates no PTR entry

[Ingo Asche]

Hi Rowland,

with the change in the failover DHCP configuration all works well now, 
I've get only only one DNS entry in the forward lookup zone.

But I just realized that there is no creating of an entry in the reverse 
lookup zone.

I might found the problem: I also have a reverse lookup zone for my IPv6 
segment and this zone is found first, don't matches the IP address given 
and so no PTR entry will be created.
