usb_id: handle ATAPI devices like SCSI devices
Some weird mass storage devices identify the disks as ATAPI/cdrom
devices, and all disks in such enclusure get the same ids which
overwrite each other, in such cases, get the typ of device from the
scsi device, which has more knowledge what kind of device it really
is.
