scaled-scene-buffer: block sharing of buffers created before reconfigure

Browse source 
This prevents potential bugs that buffers created by scaled_scene_buffers
before Reconfigure are reused by other newly created scaled_scene_buffers.

This is targeted for scaled_icon_buffer whose buffer creation depends on
server->sfdo.
