#1734570 — [PATCH stable 4.1 2/2] ipv6: Remove sit_gro_receive()

This was backported as part of 066b300e5be4 ("tunnels: Don't apply GRO
to multiple layers of encapsulation.") but nothing uses this function,
thus resulting in this build warning:

net/ipv6/ip6_offload.c:264:25: warning: 'sit_gro_receive' defined but
not used [-Wunused-function]
 static struct sk_buff **sit_gro_receive(struct sk_buff **head,
                         ^
Just drop it for now.

Fixes: 066b300e5be4 ("tunnels: Don't apply GRO to multiple layers of encapsulation.")
