Description:
------------
[regression] dns_get_record does not return false on dns server failure

When doing a nslookup for this domain: radioantwerpen.be the response is:

;; Got SERVFAIL reply from 83.149.80.123, trying next server
Server:		83.149.80.123
Address:	83.149.80.123#53

** server can't find radioantwerpen.be: NXDOMAIN

Note:
-----
This worked on PHP version 5.5x, but when I upgraded to 5.6.26 this error occurred. The same error occurs on the production server, which is a different machine with a different OS, but same PHP version.

This is a regression from bug: #53092  ( https://bugs.php.net/bug.php?id=53092 ) . It was closed in 2014.



Test script:
---------------
$url = "radioantwerpen.be";
$result = dns_get_record($url);
print_r($result);

Expected result:
----------------
return empty array

Actual result:
--------------
throws "Warning: dns_get_record(): A temporary server error occurred. in ..."
and returns nothing (no array)
