[PATCH 07/37] scsi: core: use 16-bits defined sense codes

[Damien Le Moal <dlemoal@kernel.org>]

Refactor the SCSI core code to use the 16-bits sense_code field of
struct scsi_sense_hdr and struct scsi_failure and replace all hard-coded
additional sense codes and additional sense code qualifiers with the enum
values defined in include/scsi/scsi_sense.h. This helps with code clarity
as the sense codes being processed are easier to test and self-documented.

No functional change intended.
