`AccessibleIconChoiceCtrl::getAccessibleChildCount` returns the the number of elements in the `SvxIconChoiceCtrl_Impl::maEntries` vector, and `SvtIconChoiceCtrl->GetEntry` returns the the element at the given index. Given the index check above, a valid entry should always be there, so drop the extra check that would throw a RuntimeException in `AccessibleIconChoiceCtrl::getAccessibleChild`. The `pEntry` isn't otherwise used right here anyway.
