net/ice/base: delay less

Browse Source 
Shorten the delay for SQ responses, but increase the number of loops.
Max delay time is unchanged, but some operations complete much more
quickly.

In the process, add a new define to make the delay count and delay time
more explicit, and simplify the code so it's the same for both switch
and NIC mode. Add comments to make things more explicit.
