block/raw-posix: avoid bogus fixup for cylinders on DASD disks

large volume DASD that have > 64k cylinders do claim to have
0xFFFE cylinders as special value in the old 16 bit field. We
want to pass this "token" along to the guest, instead of
calculating the real number. Otherwise qemu might fail with
"cyls must be between 1 and 65535"
