esp: choose the correct inner protocol for GSO on inter address family tunnels
Commit 23c7f8d7989e ("net: Fix esp GSO on inter address family tunnels.") is incomplete. It passes to skb_eth_gso_segment the protocol for the outer IP version, instead of the inner IP version, so we end up calling inet_gso_segment on an inner IPv6 packet and ipv6_gso_segment on an inner IPv4 packet and the packets are dropped. This patch completes the fix by selecting the correct protocol based on the inner mode's family.
