Fix bug #73331 - do not try to serialize/unserialize objects wddx can not handle

Proper soltion would be to call serialize/unserialize and deal with the result,
but this requires more work that should be done by wddx maintainer (not me).
static PHP_METHOD(PDOStatement, nextRowset)
{
	PHP_STMT_GET_OBJ;

	if (!stmt->methods->next_rowset) {
		pdo_raise_impl_error(stmt->dbh, stmt, "IM001", "driver does not support multiple rowsets" TSRMLS_CC);
		RETURN_FALSE;
	}

	PDO_STMT_CLEAR_ERR();

	if (!pdo_stmt_do_next_rowset(stmt TSRMLS_CC)) {
		PDO_HANDLE_STMT_ERR();
		RETURN_FALSE;
	}

	RETURN_TRUE;
}
