mqtt_header_state_t was added by commit 0450bd009397 ("MQTT Client: Added support for receiving empty payload"),
but it's no longer used since commit fd564b1f1733 ("client receive: refactor receive to read only one message to fragment only payload for longer messages").
Thus remove the unused mqtt_header_state_t.
