Fix if already send error to http client, do not callback. (#19668)

Fixed #10435

HttpListener already closes the Response object, closes the HTTP Client connection, and then sets the value of Response.StatusCode again. If so, an ObjectDisposedException is thrown.

```
Unhandled Exception:
System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'System.Net.HttpListenerResponse'.

If an error is sent to the HTTP client while processing a request, it is patched so that the next process is not executed anymore.

Backport of #19664.
