This patch exports blk_register_queue().
blk_register_queue() is called through add_disk().
Request-based dm defers queue allocation/initialization until
a mapping table is loaded, since the way to initialize queue
is different between bio-based mapping and request-based mapping.
So request-based dm needs to call add_disk() and blk_register_queue()
separately.
