esp6: fix memleak on error path in esp6_input
This ought to be an omission in e6194923237 ("esp: Fix memleaks on error paths."). The memleak on error path in esp6_input is similar to esp_input of esp4. Fixes: e6194923237 ("esp: Fix memleaks on error paths.") Fixes: 3f29770723f ("ipsec: check return value of skb_to_sgvec always") Signed-off-by: Zhen Lei <thunder.leizhen@huawei.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
