WGC capturer now fails with error when source is closed

When refactoring the WGC capture path, the check of a closed source
had been placed at a level where the notification of a closed source
was left without being detected since the error message was never
provided to the main WgcCapturerWin::CaptureFrame() which sends the
error message up to the client.

This trivial change ensures that WgcCapturerWin::CaptureFrame() returns
with DesktopCapturer::Result::ERROR_PERMANENT as soon as
WgcCaptureSession::OnItemClosed() has been triggered and it will
ensure that the WGC capture session stops and that any attached
MediaStreamTrack will signal its onended event as expected.
