QTableView: do not draw grid behind last section

Browse Source 
QTableView::paintEvent() drawed the grid lines behind the last section
when the region to repaint contained rects which were completely
behind the last section.
This also lead to unnecessary repaints for cells inside rect.top() to
rect.bottom()
