[PATCH v6 5/8] scsi: hisi_sas: use sas_find_attathed_phy_id() instead of open coded

From: Jason Yan
Date: Wed Sep 28 2022 - 02:39:54 EST


The attached phy finding is open coded. Now we can replace it with
sas_find_attached_phy_id(). To keep consistent, the return value of
hisi_sas_dev_found() is also changed to -ENODEV after calling
sas_find_attathed_phy_id() failed.
