[PATCH] block: fix userspace documentation reference for del_gendisk()

[Luis Chamberlain <mcgrof@kernel.org>]

Commit b5bd357cf8b ("block: add docs for gendisk / request_queue refcount
helpers") has a typo where it references drivers for del_gendisk() when we
instead meant userspace, as the reference is to the userspace experience.
This fixes this.
