core/place: Simplify meta_window_place

Browse Source 
This is a preparatory commit, it refactors away of the
done_check_denied_focus label, simplifying the control flow.

The only functional difference is that now the auto-maximization when
windows don't fit the work_area is always applied.

The next commits will adapt find_next_cascade to properly handle this.
