Description:
------------
When I call an MSSQL stored procedure using PDO DBLIB that returns multiple rowsets, When I request the next row set, PDO throws an exception.

The same query using sqlsrv in a Windows environment works as normal.

Test script:
---------------
<?php

$pdo = new PDO('dblib:server=example.com,dbname=db1', 'user', 'password');
$stmt = $pdo->prepare('EXEC [dbo].[spProcedure] ?,?,?');
$stmt->bindParam(1, 'test');
$stmt->bindParam(2, 'test');
$stmt->bindParam(3, 'test');

$stmt->execute();

$result = $stmt->fetch();

$stmt->nextRowset();

$result2 = $stmt->fetch();

Actual result:
--------------
SQLSTATE[HY000]: General error: PDO_DBLIB: dbresults() returned FAIL
