In case of using simplefb or another conflicting framebuffer,
call drm_aperture_remove_framebuffers() to remove memory allocated.

Signed-off-by: Yannick Fertre <yannick.fertre@foss.st.com>

The patch should have contained a note that this is version 2 of the 
change with a short changelog. Anyway

Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de>

Best regards
