blocK: Restore barrier support for md and probably other virtual devices.
The next_ordered flag is only meaningful for devices that use __make_request.
So move the test against next_ordered out of generic code and in to
__make_request
Since this test was added, barriers have not worked on md or any
devices that don't use __make_request and so don't bother to set
next_ordered. (dm explicitly sets something other than
QUEUE_ORDERED_NONE since
commit 99360b4c18f7675b50d283301d46d755affe75fd
but notes in the comments that it is otherwise meaningless).
