[PATCH v9 10/13] scsi: scsi_proto: refine the definition of storage element health

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

A disk may report the health of a storage element as being within or
outside of the manufacturer's specification limits using a range of values
for the health field. However, in scsi_proto.h, we only define the
start of each range using the SCSI_PHYS_ELEM_HEALTH_WITHIN_SPEC_LIMITS and
SCSI_PHYS_ELEM_HEALTH_OUTSIDE_SPEC_LIMITS enum value.

Define the full range by renaming SCSI_PHYS_ELEM_HEALTH_WITHIN_SPEC_LIMITS
to SCSI_PHYS_ELEM_HEALTH_WITHIN_SPEC_LIMITS_MIN and by defining the
healthy range end with SCSI_PHYS_ELEM_HEALTH_WITHIN_SPEC_LIMITS_MAX. The
same treatment is done for the outside range with the renaming of
SCSI_PHYS_ELEM_HEALTH_OUTSIDE_SPEC_LIMITS to
SCSI_PHYS_ELEM_HEALTH_OUTSIDE_SPEC_LIMITS_MIN, and the definition of the
range upper value with SCSI_PHYS_ELEM_HEALTH_OUTSIDE_SPEC_LIMITS_MAX.
