[Samba] DNS /16 reverse zone issues with children and octets

[Mani Wieser]

Hi Paully

I can help with showing the "subgroup" 0: instead of @ use 0

samba-tool dns query dc3 130.130.in-addr.arpa 0 ALL

the additional 0 might be a bug in 4.7, which is end of life; I would 
suggest to upgrade first......but Rowland will know more about it probably.
