floppy: fix use-after-free in module load failure path
Commit 488211844e0c ("floppy: switch to one queue per drive instead of
sharing a queue") introduced a use-after-free. We do "put_disk()" on
the disk device _before_ we then clean up the queue associated with that
disk.
Move the put_disk() down to avoid dereferencing a free'd data structure.
