GAS: Fix additional comeback delay with status code 95

Browse source 
The special case of non-zero status code used in a GAS Comeback Response
frame to indicate that additional delay is needed before the response is
available was not working properly. This case needs to allow the status
code check to be bypassed for the comeback case prior to having received
any response data.
