rust: device: fix device context of Device::parent()
Regardless of the DeviceContext of a device, we can't give any
guarantees about the DeviceContext of its parent device.
This is very subtle, since it's only caused by a simple typo, i.e.
Self::from_raw(parent)
which preserves the DeviceContext in this case, vs.
Device::from_raw(parent)
which discards the DeviceContext.
(I should have noticed it doing the correct thing in auxiliary::Device
subsequently, but somehow missed it.)
Hence, fix both Device::parent() and auxiliary::Device::parent().
