Fix an edge case updating rDNS on a netblock. If all but one per-IP field
is blank, and the remaining field is cleared, the removal wouldn't be sent
to dnsadmin because the hash wouldn't have that IP as a key.

Fixed with an extra flag field indicating "this IP had a DNS name", so we
can explicitly set the hash value to so it'll be cleared when passed
down the chain.
