vt-d: Fixup when mapping devices on non-PCIe buses

The source-id for transactions on non-PCIe buses seem to originate
from devfn=0 on the secondary bus behind the bridge.  Map that ID as
well when assigning the device.  The ID to use in these scenarios is
not particularly well documented anywhere.
