block: Adjust elv_iosched_show to return "none" for bio-based DM
Bio-based DM doesn't use an elevator (queue is !blk_queue_stackable()).
Longer-term DM will not allocate an elevator for bio-based DM. But even
then there will be small potential for an elevator to be allocated for
a request-based DM table only to have a bio-based table be loaded in the
end.
Displaying "none" for bio-based DM will help avoid user confusion.
