xwayland: Factor out focus_next_surface() from unmanaged_handle_unmap()

Browse source 
- Eliminate multiple "return" paths in unmanaged_handle_unmap(), which
  were a bug waiting to happen.
- Use wl_list_for_each_reverse() rather than wl_list_for_each() to find
  the topmost (most-recently-created) unmanaged surface.
- Only call desktop_focus_topmost_mapped_view() if the unmapped surface
  was actually focused.
