blk_cleanup_disk is nothing but a trivial wrapper for put_disk now,
so remove it.

Set the queue dying flag and call blk_mq_exit_queue from del_gendisk for
all disks that do not have separately allocated queues, and thus remove
the need to call blk_cleanup_queue for them.

Rename blk_cleanup_disk to blk_mq_destroy_queue to make it clear that
this function is intended only for separately allocated blk-mq queues.

This saves an extra queue freeze for devices without a separately
allocated queue.

This was only used by the ide-cd driver, which went away in
commit b7fb14d3ac63 ("ide: remove the legacy ide driver")
so we might as well take advantage of that and get rid of
this hook as well.

There is no need to user boiler plate code to specify a set of base
directories we're going to stuff sysctls under.  Simplify this by using
register_sysctl() and specifying the directory path directly.
