Subject: ipv6: ip6_make_skb() needs to clear cork.base.dst

From: Eric Dumazet <[email protected]>

[ Upstream commit 95ef498d977bf44ac094778fd448b98af158a3e6 ]

In my last patch, I missed fact that cork.base.dst was not initialized in ip6_make_skb() :

If ip6_setup_cork() returns an error, we might attempt a dst_release() on some random pointer.
