shell: Don't move or reconfigure surfaces until we get the new buffer

Browse source 
Going from fullscreen to toplevel will restore the surface position
immediately.  This will move the fullscreen surface to where the toplevel
surface was before, which will flicker for a frame of two before the
resized, non-fullscreen buffer is attached.

Instead, only change the surface geometry when we get the new buffer.
