====================
net: nixge: Minor cleanups

in preparation of my 64-bit support series, here's some
minor cleanup in preparation that gets rid of unneccesary
accesses to the descriptor application fields.

I've confirmed that the hardware does not access the fields
in all our configurations.
====================
