[Ldap] Warning on reset pagination

**Symfony version(s) affected**: 5.1.8

**Description**  
After #38392 \Symfony\Component\Ldap\Adapter\ExtLdap\Query::resetPagination returns warning from Adapter/ExtLdap/Query.php::239

```
Warning: ldap_parse_result() expects parameter 2 to be resource, int given
```

I can suppose that cause is on Adapter/ExtLdap/Query.php::177
