[SCSI] Revert "[SCSI] libsas: fix sas port naming"
This reverts commit a692b0eec5efae382dfa800e8b4b083f172921a7. 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.
