Fix reconnect loop

The 'close' listener is called when the socket is destroyed, which
initiates another reconnect attempt. This reconnect attempt disconnects
the new connection created by this control flow after the `retryDelay`.
To avoid an endless reconnect loop, we need to remove the 'close'
listener here before destroying the socket.
