block: fix leaking minors of hidden disks
The major/minor of a hidden gendisk is not propagated to the block
device because it is never registered using bdev_add. But the lack of
bd_dev also causes the dynamic major minor number not to be freed.
Assign bd_dev manually to ensure the dynamic major minor gets freed.
Based on a patch by Keith Busch.
