block: allow initialization of previously allocated request_queue
blk_init_queue() allocates the request_queue structure and then
initializes it as needed (request_fn, elevator, etc).
Split initialization out to blk_init_allocated_queue_node.
Introduce blk_init_allocated_queue wrapper function to model existing
blk_init_queue and blk_init_queue_node interfaces.
Export elv_register_queue to allow a newly added elevator to be
registered with sysfs. Export elv_unregister_queue for symmetry.
These changes allow DM to initialize a device's request_queue with more
precision. In particular, DM no longer unconditionally initializes a
full request_queue (elevator et al). It only does so for a
request-based DM device.
