[SCSI] sd: add fix for devices with last sector access problems
This patch adds a new scsi_device flag (last_sector_bug) for devices which contain a bug where the device crashes when the last sector is read in a larger then 1 sector read. This is for example the case with sdcards in the HP PSC1350 printer cardreader and in the HP PSC1610 printer cardreader.
