If an non-confirmable observe response was triggered, and there was already a CON message outstanding, then the observe response would not get sent in error. [Example being a observe response following a Ping 0.00 that has not yet had a reply] The fix is to check whether the observe request is non-confirmable and there are less than COAP_OBS_MAX_NON already sent to allow it to get sent.
