QMenu::popup(): don't change the menu's screen if called from exec()
Since b3fc5e1ea3eb4fe838ac716aaca4efaa5de5a814,
topData()->initialScreenIndex has always been short-lived: it only
remembers the screen in case the widget parent is a QDesktopScreenWidget
(gotten from QDesktopWidget::screen()), only until the window is
created. Then it is reset. In the case of exec() we need to avoid
calling setScreen() twice, because that would set the screen once, then
forget which screen it was supposed to be on, then set the screen again
when exec() calls popup(). This is achieved by using the stored
eventLoop pointer to detect that popup() is being called from exec(),
and avoid calling setScreen() a second time in popup(), because exec()
already needed to call createWinId() before it created the event loop.
