scsi_report_lun_scan — Scan using SCSI REPORT LUN results
which target
Zero or a mix of BLIST_NOLUN, BLIST_REPORTLUN2, or BLIST_NOREPORTLUN
nonzero if we can skip code only needed on first scan
Fast scanning for modern (SCSI-3) devices by sending a REPORT LUN command. Scan the resulting list of LUNs by calling scsi_probe_and_add_lun.
If BLINK_REPORTLUN2 is set, scan a target that supports more than 8 LUNs even if it's older than SCSI-3. If BLIST_NOREPORTLUN is set, return 1 always. If BLIST_NOLUN is set, return 0 always.
