loader: Remove the device_info in the layer chain structure

    Simplifies code, the loader device structure is passed down from
    trampoline code to terminator code via the pDevice parameter. It doesn't
    need to be added to this pCreatInfo pNext list structure.

    Layers which modifiy pDevice whould do it on the way up the chain not going
    down the chain.
