KItemListContainer: show only the scroll bar that is needed

Up to now, KItemListContainer would show both a vertical and
horizontal scroll bar after a view mode change. This commit
fixes that by setting the maximum and the value of the scroll
bar that is not needed to 0 in
KItemListContainer::updateScrollBars().
