When fbdev emulation is disabled it is not a good idea to call into
the core fb_set_suspend() function as this will cause suspend and
resume to fail. Also ifbdev->fb is null so the defeference farther
down will oops. Nothing in that path is needed in this case so bail
early when ifbdev->fb is null.
