Subject: adding missing rcu_read_unlock in ipxip6_rcv

From: "Nikita V. Shirokov" <[email protected]>

[ Upstream commit 74c4b656c3d92ec4c824ea1a4afd726b7b6568c8 ]

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)
