    Vulkan: Fix setupDraw when VK_EXT_transform_feedback is not enabled
    
    There's no dirty bit handler if VK_EXT_transform_feedback disabled, but
    we're setting that dirty bit in syncState. This results in calling a null
    method pointer. Skip the invalidate if the extension is not enabled.

    [This stack is from the added assert; calling a null function pointer
    crashes without producing a useful stack trace.]
