[Gtk] Compiler warning: comparisons like 'X<=Y<=Z' do not have their mathematical meaning

[Magnus Boman]

Compiler complains about "comparisons like 'X<=Y<=Z' do not have their mathematical meaning" in WebCore/platform/graphics/gtk/MediaPlayerPrivateGStreamer.cpp

Here's a patch. Not sure if I got it right though :-)

That's clearly a bug. Would you be willing to submit a patch for review, as described in <http://webkit.org/coding/contributing.html>?

Philippe,
I don't mind. Just wasn't sure that the logic was according to my patch.
