net: mqtt: Return -1 if keepalive messages are disabled. In mqtt_keepalive_time_left(), return -1 if keep alive messages are disabled by setting CONFIG_MQTT_KEEPALIVE=0. This allows to use mqtt_keepalive_time_left() directly as an input for poll(). If no keep-alive is expected, -1 would indicate that poll() can block until new data is available on the socket.
