Subject: ipv6: Fix leak in ipv6_gso_segment().
From: "David S. Miller" <davem@xxxxxxxxxxxxx>
[ Upstream commit e3e86b5119f81e5e2499bea7ea1ebe8ac6aab789 ]
If ip6_find_1stfragopt() fails and we return an error we have to free
up 'segs' because nobody else is going to.
Fixes: 2423496af35d ("ipv6: Prevent overrun when parsing v6 header options")
