The TX event for the next frame in the sequence might be received before the TX status for the final GAS response frame is processed. This used to result in the Config Result getting discarded and the negotiation not completing successfully on the Configurator side. Accept the Config Result message as an indication of the final GAS response frame having went through fine even if the TX status has not yet been processed to avoid this issue from a potential race condition on kernel events.
