[SCSI] scsi_scan.c: fix compile warnings
drivers/scsi/scsi_scan.c: In function `scsi_probe_and_add_lun': drivers/scsi/scsi_scan.c:926: warning: unused variable `vend' drivers/scsi/scsi_scan.c:926: warning: unused variable `mod' drivers/scsi/scsi_scan.c: At top level: drivers/scsi/scsi_scan.c:829: warning: `scsi_inq_str' defined but not used Fix those, tighten up the (somewhat poorly-designed) logging macro and fix some coding-style warts.
