ses: fix discovery of SATA devices in SAS enclosures
The current discovery routines use the VPD 0x83 inquiry page to find the device SAS address and match it to the end point in the enclosure. This doesn't work for SATA devices because expanders (or hosts) simply make up an endpoint address for STP and thus the address returned by the VPD page never matches. Instead of doing this, for SAS attached devices, match by the direct endpoint address instead. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

Enclosures are devices sitting on or in SCSI backplanes that
manage devices. If you have a disk cage, the chances are that
