iptunnel: make rx/tx bytes counters consistent

Browse Source 
This was already done a long time ago in
commit 64194c31a0 ("inet: Make tunnel RX/TX byte counters more consistent")
but tx path was broken (at least since 3.10).

Before the patch the gre header was included on tx.

After the patch:
$ ping -c1 192.168.0.121 ; ip -s l ls dev gre1
PING 192.168.0.121 (192.168.0.121) 56(84) bytes of data.
64 bytes from 192.168.0.121: icmp_req=1 ttl=64 time=2.95 ms
