    cogl-winsys-glx: Fix the comparison in find_onscreen_for_xid
    
    The comparison for finding onscreen framebuffers in
    find_onscreen_for_xid had a small thinko so that it would ignore
    framebuffers when the negation of the type is onscreen. This ends up
    doing the right thing anyway because the onscreen type has the value 0
    and the offscreen type has the value 1 but presumably it would fail if
    we ever added any other framebuffer types.
