HTTP2 Error handling is broken when Http2DirectAttribute is enabled

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
