[SCSI] Improve SCSI_LOGGING Kconfig entry
The Kconfig entry for SCSI_LOGGING refers the reader to
drivers/scsi/scsi.c, but I didn't find any useful information
there. There is certainly logging code in that file, but the
logging types and logging levels are described in
drivers/scsi/scsi_logging.h.
Also, the procfs file referred to in the section is incorrect.
It should be /proc/sys/dev/scsi/logging_level and not
/proc/scsi/scsi.
