Ticket History #6696: gss_accept_sec_context doesn't produce error tokens

The mechglue for gss_accept_sec_context suppresses error tokens which means that an initiator who is waiting for a response after receiving GSS_S_CONTINUE­_NEEDED is never notified that there’s a problem.  It appears the code has been this way ever since the mechglue was introduced.  This fixes it for me:
