It seems after Http2DirectAttribute was introduced some error cases when connectionType is ConnectionTypeHTTP2, should also be handled when connectionType is ConnectionTypeHTTP2Direct.

Steps to reproduce:

1. Create QNetworkRequest
2. setAttribute(QNetworkRequest::Http2DirectAttribute, true);
3. POST request when server is not started

Expected behaivor:

3. Error occured because connection refused

Actual behaivor:

3. Nothing happens, reply stays alive till application terminated

See attached application.

Issue both reproducable with SSL enabled and disabled
