Dongwon Kim 64f1359bd0 ui/gtk: prevent ui lock up when dpy_gl_update called again before current draw event occurs 
A warning, "qemu: warning: console: no gl-unblock within" followed by
guest scanout lockup can happen if dpy_gl_update is called in a row
and the second call is made before gd_draw_event scheduled by the first
call is taking place. This is because draw call returns without decrementing
gl_block ref count if the dmabuf was already submitted as shown below.

(gd_gl_area_draw/gd_egl_draw)

        if (dmabuf) {
            if (!dmabuf->draw_submitted) {
                return;
            } else {
                dmabuf->draw_submitted = false;
            }
        }

So it should not schedule any redundant draw event in case draw_submitted is
already set in gd_egl_fluch/gd_gl_area_scanout_flush.
