swim: add a floppy registration bool which triggers del_gendisk()
Instead of calling del_gendisk() on exit alone, let's add
a registration bool to the floppy disk state, this way this can
be done on the shared caller, swim_cleanup_floppy_disk().
This will be more useful in subsequent patches. Right now, this
just shuffles functionality out to a helper in a safe way.
