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")
