The print in ndesc_display_ring() sends the des2 and des3
to the pr_info() without passing them through the relevant
conversion to cpu order.
Fix the (prototype) sparse warnings by using le32_to_cpu():

I agree on the principle, but this isn't a fix so this'll have to wait
until net-next re-opens :)
Thanks,
