In the mqtt5 protocol the broker can disconnect the client with a disconnect packet. This packet contains a reason value that can be useful for certain applications in which it is important to know the reason of disconnection. While the client is connected is possible that a disconnect packet is reaceived by the broker to force a disconnection. Before this patch this approach causes a generic error on transport in case of disconnection from the broker. If the packet is managed before getting an error it is possible to save the reason code in the disconnect_return_code variable in the error_handle, and dispatch the disconnect event that can be managed by the application event loop, that now can know the reason of disconnection from the broker. Reset the variable in case of error. Signed-off-by: Flavia Caforio <flavia.caforio@amarulasolutions.com>
