intel/eu: Don't set notify descriptor field of gateway barrier message.

Browse Source 
Apparently this field was removed on SKL, and according to the
hardware docs for previous platforms "This field is only valid for a
ForwardMsg message. It is ignored for other messages. The BarrierMsg
message always increments the N0 notification counter".
