Avoid flooding log during DXGI screen capture error handling

Due to an error handling bug, the DXGI screen capture would flood the log
when facing lost duplication interface. This can happen for example when
pushing Ctr+Alt+Del while screen capturing is ongoing.

This change does not implement recovery after lost duplication interface,
but prevents flooding the log by avoiding repeatedly calling
IDXGIOutputDuplication::ReleaseFrame
