Dan Williams b4698d8858 [SCSI] Revert "[SCSI] libsas: fix sas port naming" 
This reverts commit a692b0eec5.

Tom reports:

[    8.741033] ------------[ cut here ]------------
[    8.741038] WARNING: at fs/sysfs/dir.c:508 sysfs_add_one+0xc1/0xf0()
[    8.741040] Hardware name: To Be Filled By O.E.M.
[    8.741041] sysfs: cannot create duplicate filename

...and missing 2 out of 4 drives connected to mvsas.  Commit a692b0ee
made the assumption that all the phy ids an lldd registers to libsas are
unique.  However, in the "multi-chip" case mvsas does a rather annoying
duplication of phy ids in the array passed to libsas.  So, for example,
chip0 has phy0-3 at ha phy index 0-3 and chip1 has its phy0-3 at ha phy
index 4-7.  The more natural model would be to create a scsi_host (and
sas_ha) per chip (controller), but for now revert the naming fix which
unfortunately means dealing with unpredictable end-device names for a
bit longer.
