rS308216: In rtadvd, interface lookup calls if_indextoname() many times in a loop,
Summary

In rtadvd, interface lookup calls if_indextoname() many times in a loop,
(it takes a long time on systems with many interfaces)
without reason and without checking its return value.

This is fixed by this patch.

Test Plan

Our automated tests show no regression.
This patch is already included in Stormshield Network products.
