[SCSI] usbstorage: use last_sector_bug flag universally

Browse source 
This patch sets the last_sector_bug flag to 1 for all USB disks. This is
needed to makes the cardreader on various HP multifunction printers work.

Since the performance impact is negible we set this flag for all USB disks to
avoid an unusual_devs.h nightmare.
