From: Hideyuki Yamashita <yamashita.hideyuki@po.ntt-tx.co.jp>

clear_forward_info() always initializes path[0] of g_forward_info[id].
It is a bug and causes stopping forwarding accidentally if path[0] is
referenced by spp_forward().

This patch changes initializing as path[info->upd_index] instead of 0.
It also includes refactoring to be simple by using local vars.
