Refactor the HP sw device handler driver 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.
