Fix DRIExtensionInit() to not register callbacks when it hasn't been 

initialized for the current server generation. Fixes a problem where it
    would use stale private index and blow up in colorful ways if no driver
    called DRIScreenInit() on the second generation (which happens due to a
    bug in radeon that i'll fix separately). Note: clearing the index in
    DRIReset() wouldn't work as DRIReset() is called before the
    CloseScreen() chain
