    framebuffer: avoid redundant calls to _init_bits
    
    There is no need to call _cogl_framebuffer_init_bits for the draw and
    read buffers each time we flush the framebuffer state since we will
    always re-sync with gl if necessary when the
    cogl_framebuffer_get_red/green/blue/alpha_bits functions are called.
