svga: don't use uninitialized framebuffer state
Only the first 'nr_cbufs' color buffers in the pipe_framebuffer_state are valid. The rest of the color buffer pointers might be unitialized. Fixes a regression in the piglit fbo-srgb-blit test since changes in the gallium blitter code. NOTE: This is a candidate for the 9.0 branch (just to be safe).
