Log only the first line of user input on PROXY protocol v1 error.
Previously, all received user input was logged. If a multi-line text was received from client and logged, it could reduce log readability and also make it harder to parse nginx log by scripts. The change brings to PROXY protocol the same behavior that exists for HTTP request line in ngx_http_log_error_handler().
