[SCSI] ses: fix problems caused by empty SES provided name
We use the name provided by SES to name objects. An empty name is legal in SES but causes problems in our generic device hierarchy. Fix this by falling back to a number if the name is either NULL or empty. Also fix a secondary bug spotted in that dev_set_name(dev, name) uses a string format and so would go wrong if name contained a '%'.
