Since the factory and adapter interfaces may be wrapped, calling
IDXGIAdapter_EnumOutputs() on a wrapped adapter may in turn return a wrapped
output interface. Things would go poorly from there, so make sure we have a
unwrapped interface here. Alternatively, we could have allowed output
interfaces to be wrapped, but tests show that e.g.
IDXGISwapChain_SetFullscreenState() fails when passed a wrapped output
interface.
