scsi: pm80xx: Fix pm8001_abort_task() for chip_8006 when using an expander
[ Upstream commit ad70c6bc776b53e61c8db6533c833aff0ff5da8b ]
For a direct attached device, attached_phy contains the local phy id.
For a device behind an expander, attached_phy contains the remote phy
id, not the local phy id.
The pm8001_ha->phy array only contains the phys of the HBA. It does not
contain the phys of the expander.
Thus, you cannot use attached_phy to index the pm8001_ha->phy array,
without first verifying that the device is directly attached.
Use the pm80xx_get_local_phy_id() helper to make sure that we use the
local phy id to index the array, regardless if the device is directly
attached or not.
