remove recently added cache from KeyVariety
Adding that field broke the Read/Show serialization back-compat,
and also the Eq and Ord instances were not blinded to it, which broke
git annex fsck and probably more.

I think that the new approach used in formatKeyVariety will be nearly
as fast, but have not benchmarked it.
