### Motivation When there are multiple pending requests in the same `ClientConnection`, if one request failed with a retryable error, e.g. the `ServiceUnitNotReady` error when finding the owner broker of a topic, the socket will be closed in `checkServerError` and `close()` will be called subsequently in `handleRead` (`err` is `eof` or `operation_failed`). However, the default value of 1st parameter is `ResultConnectError` for `close`, which is not retryable. ### Modifications If the connection is disconnected by the client, pass `ResultDisconnected` to `close` and treat it as retryable. closeSocket is replaced with close(ResultDisconnected) to avoid the connection being the status that socket is closed but TLS stream is not closed.
