cdrom: Fix info leak/OOB read in cdrom_ioctl_drive_status
commit 8f3fafc9c2f0ece10832c25f7ffcb07c97a32ad4 upstream.
Like d88b6d04: "cdrom: information leak in cdrom_ioctl_media_changed()"
There is another cast from unsigned long to int which causes
a bounds check to fail with specially crafted input. The value is
then used as an index in the slot array in cdrom_slot_status().
