  libsas disks can have non-unique by-path names

Bug description:
  [Impact]
  Multiple disks in a system can end up having the same BY_PATH name, making the corresponding symlinks in /dev/disk/by-path non-unique. This can result in a user performing an operation on the wrong disk, possibly resulting in data loss.

  [Test Case]
  $ 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

  
  Notice that there is no symlink for /dev/sdc.

  [Fix]
  ffeafdd2bf0b2 scsi: libsas: Fix rphy phy_identifier for PHYs with end devices attached

  [Regression Risk]
  This may change the by-path symlinks for disks on the system. While the new name would be the correct one - users maybe relying on the incorrect version. This could result in an unbootable system, requiring manual intervention to repair.
