Fix logging of incorrect status codes for disconnected requests (#12580)
The status code of requests must always be set, regardless of client
disconnection, otherwise they will always be logged as 200!.

Broken for `respond_with_json` in
f48792eec43f893f4f893ffdcbf00f8958b6f6b5.
Broken for `respond_with_json_bytes` in
3e58ce72b42f2ae473c1e76a967548cd6fa7e2e6.
Broken for `respond_with_html_bytes` in
ea26e9a98b0541fc886a1cb826a38352b7599dbe.
