Subject: [PATCH 01/17] batman-adv: move neigh_node->if_incoming->if_status check in find_router()

From: Antonio Quartulli <ordex@...istici.org>

Every time that find_router() is invoked, if_status has to be compared with
IF_ACTIVE. Moving this comparison inside find_router() will avoid to write it
each time.
