Subject: scsi: ses: use scsi_is_sas_rphy instead of is_sas_attached

From: Johannes Thumshirn <jthumshirn@suse.de>

commit 835831c57e9b0cccc24e96a812542875471d75b5 upstream.

Use scsi_is_sas_rphy() instead of is_sas_attached() to decide whether we
should obtain the SAS address from a scsi device or not. This will
prevent us from tripping on the BUG_ON() in sas_sdev_to_rdev() if the
rphy isn't attached to the SAS transport class, like it is with hpsa's
logical devices.
