John Garry ffeafdd2bf scsi: libsas: Fix rphy phy_identifier for PHYs with end devices attached 
The sysfs phy_identifier attribute for a sas_end_device comes from the rphy
phy_identifier value.

Currently this is not being set for rphys with an end device attached, so
we see incorrect symlinks from systemd disk/by-path:

root@localhost:~# ls -l /dev/disk/by-path/
total 0
lrwxrwxrwx 1 root root  9 Feb 13 12:26 platform-HISI0162:01-sas-exp0x500e004aaaaaaa1f-phy0-lun-0 -> ../../sdb
lrwxrwxrwx 1 root root 10 Feb 13 12:26 platform-HISI0162:01-sas-exp0x500e004aaaaaaa1f-phy0-lun-0-part1 -> ../../sdb1
lrwxrwxrwx 1 root root 10 Feb 13 12:26 platform-HISI0162:01-sas-exp0x500e004aaaaaaa1f-phy0-lun-0-part2 -> ../../sdb2
lrwxrwxrwx 1 root root 10 Feb 13 12:26 platform-HISI0162:01-sas-exp0x500e004aaaaaaa1f-phy0-lun-0-part3 -> ../../sdc3

Indeed, each sas_end_device phy_identifier value is 0:

root@localhost:/# more sys/class/sas_device/end_device-0\:0\:2/phy_identifier
0
root@localhost:/# more sys/class/sas_device/end_device-0\:0\:10/phy_identifier
0

This patch fixes the discovery code to set the phy_identifier.  With this,
we now get proper symlinks:

root@localhost:~# ls -l /dev/disk/by-path/
total 0
