scsi: mvsas: Use sas_find_attached_phy_id() instead of open coding it
The attached phy finding is open coded. Replace it with
sas_find_attached_phy_id(). To keep things consistent, the return value of
mvs_dev_found_notify() is also changed to -ENODEV after calling
sas_find_attathed_phy_id() failed.
