Kuniyuki IwashimaandGreg Kroah-Hartman 9c58c729d3 vxlan: Fix potential null-ptr-deref in vxlan_gro_prepare_receive(). ...

[ Upstream commit 30a45c0bff ]

udp_tunnel_sock_release() could set sk->sk_user_data to NULL
while vxlan_gro_prepare_receive() is running.

Let's check if rcu_dereference_sk_user_data() is NULL after
skb_gro_remcsum_init().
