This can't fail. Luben's right here. If the lldd is snooping INQUIRY
response, then the lldd is responsible for knowing how much it actually
transferred and the scsi mid layer is not on the hook for telling it
anything. We are free to play our "try different INQUIRY lengths" games
at the mid level and ignore any lldd snooping entirely.
