[SCSI] Workaround for disks that report bad optimal transfer length
Not all disks fill out the VPD pages correctly. Add a blacklist flag that allows us ignore the SBC-3 VPD pages for a given device. The BLIST_SKIP_VPD_PAGES flag triggers our existing skip_vpd_pages scsi_device parameter to bypass VPD scanning. Also blacklist the offending Seagate drive model.
