    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).
