I left nvme request / map setup as it was in Keith's work for the most
part (apart from rebases, adapting it, etc.). It appears I have some
use for prp lists, and I know Kanchan, Nitesh and Anuj already have some
patches adding sgl support and some other optimisations. Hopefully, I
addressed most all feedback from v2.
