efl_ui_win: optimize shutdown

in case we are having a scroller with a lot of elements on it, we are
spending a lot of time in stuff like recalculating clips, even if they
will never be used again.

With this freeze here, we are saving 9s shutdown time in item_container.
Which brings the overall closing time from 10s down to 1s, which is a
win IMO.
