<pre>This crash is fixed on master:
commit 971165368d22b16f248e82b3d6f4f1f1eedb764e

compositor: set surface->plane from destroyed plane to NULL
In drm backend, the cursor_surface->plane point to
drm_output->cursor_plane.when this output is removed,
drm_output->cursor_plane is destroyed, butcursor_surface->plane
still point to destroyed plane. So once mouse move to this
cursor_surface and system will repaint this cursor_surface,
segment fault will generate in weston_surface_damage_below() function.
V2:
-set surface->plane to NULL whose plane point to unplugged output,
then change weston_surface_damage_below() to do nothing if
surface->plane is NULL (Kristian)
-set surface->plane to NULL in weston_surface_unmap(),
so that all surfaces that have a non-NULL plane pointer wil be
on compositor->surface_list (Kristian).
