QComboBox: don't call data(invalid index) on the underlying model

Browse Source 
QComboBoxPrivate::itemIcon() wasn't checking for an invalid index,
unlike QComboBoxPrivate::itemText().
QComboBoxPrivate::setCurrentIndex calls updateLineEditGeometry,
which calls QComboBox::itemIcon, even for an invalid combobox.

Pick-to: 6.5 6.2
