[RFC 01/12] floppy: fix add_disk() assumption on exit

[Luis Chamberlain <mcgrof@kernel.org>]

Even if the queue was cleaned up on exit,
putting the disk *is* still required, and
likewise, blk_cleanup_queue() on a null queue
should be a no-op now, after the patch titled
"block: skip queue if NULL on blk_cleanup_queue()"
so it is safe to use even if the queue is NULL.
