hostdev: Use actual device when reattaching
hostdev: Use actual device when reattaching

Instead of forcing the values for the unbind_from_stub, remove_slot
and reprobe properties, look up the actual device and use that when
calling virPCIDeviceReattach().

This ensures the device is restored to its original state after
reattach: for example, if it was not bound to any driver before
detach, it will not be bound forcefully during reattach.
