Unlike a plain `net/http/client.Do()`, requests made through client/request use the `sendRequest` function, which parses the server response, and may convert non-transport errors into errors (through `cli.checkResponseErr()`). This means that we cannot assume that no reader was opened if an error is returned. This patch changes various locations where `ensureReaderClosed` was only called in the non-error situation, and uses a `defer` to make sure it's always called. `ensureReaderClosed` itself already checks if the response's body was set, so in situations where the error was due to a transport error, calling `ensureReaderClosed` should be a no-op.
