[intelxl] Split out ring creation from context programming
The virtual function driver will use the same transmit and receive
descriptor ring structures, but will not itself construct and program
the ring context. Split out ring creation and destruction from the
programming of the ring context, to allow code to be shared between
physical and virtual function drivers.
