Attached is a patch that solves the bug #56022.

The first PINGRESP (keep-alive) was sent only after 2 * MQTT_CYCLIC_TIMER_INTERVAL. If MQTT_CYCLIC_TIMER_INTERVAL = 5s and keep-alive is set to 5s too, the first PINGRESP is sent 10s after the connection.

In this case, the server (MQTT Broker) could force a disconnection if the PINGRESP message isn't received in 7-8s after connection.
