drm/i915/fb: Fix the set_tiling vs. addfb race, again
intel_frontbuffer_get() is what locks out subsequent set_tiling
changes to the bo. Thus the fence vs. modifier check must be done
after intel_frontbuffer_get(), or else a concurrent set_tiling ioctl
might sneak in and change the fence after the check has been done.
Close the race again. See commit dd689287b977 ("drm/i915: Prevent
concurrent tiling/framebuffer modifications") for the previous
instance.
