Timo Teräs f016229e30 ipv4: rate limit updating of next hop exceptions with same pmtu
The tunnel devices call update_pmtu for each packet sent, this causes
contention on the fnhe_lock. Ignore the pmtu update if pmtu is not
actually changed, and there is still plenty of time before the entry
expires.
