scsi-disk: fix reads from scsi-disk devices

Commit fcaafb1001b9c42817714dd3b2aadcfdb997b53d accidentally broke reads from
scsi-disk devices when being updated from its original form to use the new
byte-based block functions. Add the extra missing sector to offset conversion
in order to restore read functionality.
