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

Note that uas was the only driver setting these size limits from
->slave_alloc and not ->slave_configure and this makes it match
everyone else.

Looks OK to me.
