QStyleSheet/QProxyStyle: Avoid deref after setWindowFlags in polish
When invoking setWindowFlags with a QStyleSheet and QProxyStyle set, a
repolish is recursivly done creating a second QStyleSheetStyle in
QWidgetPrivate::inheritStyle due to not cleared WA_SetStyle window flag.
This leads to a use-after-free in the then following recursive call to
QStyle::polish. This patch uses the previously create QStyleSheetStyle
in the case that there is already a QStyleSheetStyle for the proxy.
Fixes: QTBUG-125513
Pick-to: 6.8 6.7
