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. Add comments to make things more explicit.
This fixes a problem with VF resets failing on with many VFs.
