Subject: [iproute PATCH] iproute: Remove useless check for nexthop keyword when setting RTA_OIF

When modifying a route we set the RTA_OIF attribute only if a device was
specified with "dev" or "oif" keyword. But for some unknown reason we
earlier alternatively check also for the presence of "nexthop" keyword,
even though it has no effect. So remove the pointless check.
