QAbstractButton: don't access nullptr in queryButtonList()
When a button has no parent, QAbstractButtonPrivate::queryButtonList()
unconditionally accessed parent which results in a nullptr access. Did
not crash because qt_qFindChildren_helper checks for nullptr and
therefore could only be found with a sanitizer.
Fixes: QTBUG-83865
