framebuffer: avoid redundant calls to _init_bits

Browse Source 
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.
