This patch exports blk_register_queue().
Request-based dm and bio-based dm will coexist, since there are
some target drivers which are more fitting to bio-based dm.
dm decides the hook type for a dm device and initializes the queue,
when a table is loaded to the dm device, not device creation time.
Then, request-based dm sets q->request_fn and wants to register
the queue correctly again.
