Hi, Su

Clang static analyzer complains that value stored to 'res' is never read.
Return the error code when sas_find_attached_phy_id() failed.

Fixes: ec64858657a8 ("scsi: pm8001: Use sas_find_attached_phy_id() instead of open coding it")

This 'Fixes' tag is not right. This commit is only a refactor and did not change the original logic here.

Thanks,
Jason
