ide: Add wwn support to IDE-ATAPI drive
Although it is possible to specify the wwn property for cdrom devices on the command line, the underlying driver fails to relay this information to the guest operating system via IDENTIFY. This is a simple patch to correct that. See ATA8-ACS, Table 22 parts 5, 6, and 9.
