cdrom_id: Fix DVD blank detection for sloppy firmware
Reportedly, many CD drive firmwares will only consider the MSB in a READ
command, thus if we request 17 blocks to be read, we'll actually only get 16 in
many cases, and thus miss out the interesting sector #17. This would lead to
falsely considering nonempty DVDs as blank.
Fetch 32 blocks now, which should work everywhere.
