 When checking the DNS RCODE after attempting to remove either forward or
 reverse DNS entries,  NameRemoveTransaction should check
 for the value NXRRSET, not NXDOMAIN.

 The pre-requisite tests are "RRSet exists" checks not "Name exists"
 checks, and hence are using the wrong RCODE value.  This causes
 deletes for entries that are not there (i.e. RCODE = NXRRSET) as
 failures when they should be treated as success.
