esp6_offload: Fix IP6CB(skb)->nhoff for ESP GRO
IP6CB(skb)->nhoff is the offset of the nexthdr field in an IPv6
header, unless there are extension headers present, in which case
nhoff points to the nexthdr field of the last extension header.
In non-GRO code path, nhoff is set by ipv6_rcv before any XFRM code
is executed. Conversely, in GRO code path (when esp6_offload is loaded),
nhoff is not set. The following functions fail to read the correct value
and eventually the packet is dropped:
xfrm6_transport_finish
xfrm6_tunnel_input
xfrm6_rcv_tnl
Set nhoff to the proper offset of nexthdr in esp6_gro_receive.
