ip_tunnel: Fix dst ref-count.

[ Upstream commit fbd02dd405d0724a0f25897ed4a6813297c9b96f ]

Commit 10ddceb22ba (ip_tunnel:multicast process cause panic due
to skb->_skb_refdst NULL pointer) removed dst-drop call from
ip-tunnel-recv.

Following commit reintroduce dst-drop and fix the original bug by
checking loopback packet before releasing dst.
