Disable overlay support when the overlay swap chain creation fails.

The current way to handle the overlay swap chain creation failure might cause
a complet black browser window, which is a very bad user experience. If we
disable overlay when the creation fails, the video playback will be able to
continue through GL composition if there is no other issue.
