MQTT client hanging on stop/destroy after connect fail

[TheRealRevK]

v4.1-dev-104-gaa087667d

If MQTT fails to connect (in this case it is cert parse issue), then trying esp_mqtt_client_stop or esp_mqtt_client_destroy just hang!

This is how MQTT failed, for reference. Probably my mistake in the cert.
