[PATCH] include/net/dsfield.h warning (2.4,2.5)

[Werner Almesberger]

This "obviously correct" patch removes code that was never used,
and that yields warnings with recent versions of gcc. (It can
always be resurrected from archives in the unlikely event that
we should ever need those few cycles it would save.)

I tried this patch with 2.5.24, but it should be fine for any 2.4
or 2.5 kernel.

Applied, thanks.
