Clang static analyzer complains that value stored to 'res' is never

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.
Hi, Jason
Thanks for your reply. But I think the logic of this code is changed.

Before this patch, we won't go to label 'found_out', and will call
PM8001_CHIP_DISP->reg_dev_req() ....
After this patch, we just free the 'pm8001_device' and return the error
code.
Or maybe I misunderstand somewhere?
