[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.

	  There are a number of things that can be used for 'token' (you can

	  find them in the source: <file:drivers/scsi/scsi.c>), and this

	  allows you to select the types of information you want, and the

	  level allows you to select the level of verbosity.

	  There are a number of logging types and you can find them in the

	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels

	  are also described in that file and they determine the verbosity of

	  the logging for each logging type.



	  If you say N here, it may be harder to track down some types of SCSI

	  problems. If you say Y here your kernel will be somewhat larger, but
