[PATCH] scsi: pm8001: return error code if no attached dev

[Su Hui]

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")
