Return an error when no name servers were returned in net_ads.c

[Richard Sharpe]

Hi folks,

Attached is a git format-patch formatted patch for
source3/utils/net_ads.c to return an error in the case I uncovered
while getting the self-test stuff working for net ads dns register etc
...

Please review and push if acceptable ...
