scsi: smartpqi: Expose SAS address for SATA drives
Remove UNIQUE_WWID_IN_REPORT_PHYS_LUN PQI feature.
This feature was originally added to solve a problem with NVMe drives, but
this problem has since been solved a different way, so this PQI feature is
no longer required for any type of drive.
The kernel was not creating symbolic links in sysfs between SATA drives and
their enclosure.
The driver was enabling the UNIQUE_WWID_IN_REPORT_PHYS_LUN PQI feature,
which causes the FW to return a WWID for SATA drives that is derived from a
unique ID read from the SATA drive itself. The driver was exposing this
WWID as the drive's SAS address. However, because this SAS address does not
match the SAS address returned by an enclosure's SES Page 0xA data, the
Linux kernel was not able to match a SATA drive with its enclosure.
