Double different discovery message for the RF (RCSwitch) module

[Odyno]

Describe the bug
Double different discovery messages are sent for the RF (RCSwitch) module:

One as MQTT DeviceTrigger on

OpenMQTTGateway/main/ZgatewayRF.ino

Lines 101 to 102 in 7fa00dd

	announceDeviceTrigger(
	false,

and one other as the MQTT Sensor on

OpenMQTTGateway/main/ZmqttDiscovery.ino

Lines 1078 to 1086 in 7fa00dd

	# ifdef ZgatewayRF
	// Sensor to display RF received value
	Log.trace(F("gatewayRFDiscovery" CR));
	char* gatewayRF[8] = {"sensor", "gatewayRF", "", "", jsonVal, "", "", ""};
	//component type,name,availability topic,device class,value template,payload on, payload off, unit of measurement
	//trc(gatewayRF[1]);
	createDiscovery(gatewayRF[0],
	subjectRFtoMQTT, gatewayRF[1], (char*)getUniqueId(gatewayRF[1], gatewayRF[2]).c_str(),

with the result of the double entity on the discovery topic:
Yellow is [MQTT DeviceTrigger], Blue is [MQTT Sensor]

To Reproduce
Steps to reproduce the behavior:

1. Enable discovery and enable RF module
2. Receive one RF message

Expected behavior
I think this behavior is anomalous: the RF module that should only send/receive the raw data.
The mqtt discovery sensor should not be sent
