Switch to the ->device_configure method instead of ->slave_configure
and update the block limits on the passed in queue_limits instead
of using the per-limit accessors.

That now looks odd.
We're taking great pains to have everything in queue_limits and avoid

Wouldn't it make sense to move that into queue_limits, too?
