    glx: Clear new FBConfig attributes to 0 by default.

    The visualSelectGroup wasn't getting set (since our DRI drivers don't
    use it), and and since it's the top priority in the sort order, you
    got random sorting of your visuals unless malloc really returned you
    new memory. This manifested as Xephyr -glamor rendering to a
    multisampled window on my system, which as you might guess was
    slightly lower performance than expected.
