Upstream: ngx_http_upstream_finalize_request(NGX_ERROR) on errors. Previously, ngx_http_upstream_finalize_request(0) was used in most cases after errors. While with current code there is no difference, use of NGX_ERROR allows to pass a bit more information into ngx_http_upstream_finalize_request().
