d3d11desktopdup: Don't ignore error DXGI_ERROR_UNSUPPORTED

Seungha Yang requested to merge seungha.yang/gst-plugins-bad:d3d11-desktop-dup-error-handle into master

Although Microsoft's DXGIDesktopDuplication example is considering the DXGI_ERROR_UNSUPPORTED as an expected error (See https://github.com/microsoft/Windows-classic-samples/tree/master/Samples/DXGIDesktopDuplication) it might not be recoverable error if application is run against a discrete GPU (See https://docs.microsoft.com/en-US/troubleshoot/windows-client/shell-experience/error-when-dda-capable-app-is-against-gpu)

Do early error out if the error happens while opening device, instead of retrying it forever.
