Replace the earlier LeapRAID ncq_cmd_prio_enable attribute with the
standard sas_ncq_prio_supported and sas_ncq_prio_enable names documented in
Documentation/ABI/testing/sysfs-block-device, and rename the per-device NCQ
priority state to match.
The earlier ncq_cmd_prio_enable name has not yet been established as part
of a released userspace ABI, so no compatibility alias is needed.
For LeapRAID, sas_ncq_prio_enable is backed by the driver's per-device NCQ
priority state and controls whether RT-class I/O requests are issued with
command priority on supported SATA devices.
Update leapraid.rst to describe the standard attribute names and paths, and
clean up the surrounding RST text for consistency with kernel documentation
style.
Also switch the capability check from open-coded VPD page 0x89 parsing to
sas_ata_ncq_prio_supported(), use kstrtobool() for the enable path, and
expose the NCQ priority attributes only for SATA devices using LeapRAID's
target-private SAS device state.
