Prepare for removing /proc/scsi from the Linux kernel
From: Bart Van Assche <bvanassche@acm.org>
The sg3_utils package is the only /proc/scsi user I know of.
Although support for systems without /proc/scsi was added to
rescan_scsi_bus.sh more than ten years ago, a few references
to /proc/scsi remain. Convert these references into the
recommended interfaces.
