[SCSI] sg: fix /proc/scsi/sg/devices when no SCSI devices
The patch "[SCSI] sg: use idr to replace static arrays" in 2.6.24-rc1 causes a bogus line to appear in /proc/scsi/sg/devices containing "-1 -1 -1 -1 -1 -1 -1 -1 -1" when there are no SCSI devices in the system. In 2.6.23, /proc/scsi/sg/devices is empty when there are no SCSI devices in the system. A similar problem exists with /proc/scsi/sg/device_strs. The following patch restores the behavior of 2.6.23.
