adding missing rcu_read_unlock in ipxip6_rcv
commit 8d79266bc48c ("ip6_tunnel: add collect_md mode to IPv6 tunnels") introduced new exit point in ipxip6_rcv. however rcu_read_unlock is missing there. this diff is fixing this v1->v2: instead of doing rcu_read_unlock in place, we are going to "drop" section (to prevent skb leakage) Fixes: 8d79266bc48c ("ip6_tunnel: add collect_md mode to IPv6 tunnels") Signed-off-by: Nikita V.
