scsi scan bug when peripheral qualifier of 3 is returned

[Mike Christie <michaelc@cs.wisc.edu>]

It looks like in previous kernels scsi_scan_target would pass 
scsi_sequential_lun_scan BLIST_SPARSELUN.

         } else if (res == SCSI_SCAN_TARGET_PRESENT) {
                 /*
                  * There's a target here, but lun 0 is offline so we
                  * can't use the report_lun scan.  Fall back to a
                  * sequential lun scan with a bflags of SPARSELUN and
                  * a default scsi level of SCSI_2
                  */
                 scsi_sequential_lun_scan(starget, BLIST_SPARSELUN,


And in the current kernel we pass it bflags.

                         /*
                          * The REPORT LUN did not scan the target,
                          * do a sequential scan.
                          */
                         scsi_sequential_lun_scan(starget, bflags,


But for SCSI_SCAN_TARGET_PRESENT bflags is not set. Is the correct fix 
to move where bflagsp gets set in scsi_probe_and_add_lun so that it gets 
set for the SCSI_SCAN_TARGET_PRESENT case, or should __scsi_scan_target 
be passing scsi_sequential_lun_scan and possibly scsi_report_lun_scan 
some default bflags values?
