dm: remove queue next_ordered workaround for barriers

This patch removes DM's bio-based vs request-based conditional setting
of next_ordered.  For bio-based DM the next_ordered check is no longer a
concern (as that check is now in the __make_request path).  For
request-based DM the default of QUEUE_ORDERED_NONE is now appropriate.

bio-based DM was changed to work-around the previously misplaced
next_ordered check with this commit:
99360b4c18f7675b50d283301d46d755affe75fd

request-based DM does not yet support barriers but reacted to the above
bio-based DM change with this commit:
5d67aa2366ccb8257d103d0b43df855605c3c086

The above changes are no longer needed given Neil Brown's recent fix to
put the next_ordered check in the __make_request path:
