Chris Pearce 7577f98b66 Bug 944088 - Make MP4Reader::Init() assume mLayersBackendType=LAYERS_NONE if it doesn't have a decoder owner. r=kinetik
This ensures that if the MP4Reader fails to get a decoder owner, we
don't abort the media load, but instead we will assume that we don't
have an advanced layers backend, and so fallback to software decoding on
Windows.
