esp6: fix memleak on error path in esp6_input

[ Upstream commit 7284fdf39a ]

This ought to be an omission in e619492323 ("esp: Fix memleaks on error
paths."). The memleak on error path in esp6_input is similar to esp_input
of esp4.

Fixes: e619492323 ("esp: Fix memleaks on error paths.")
Fixes: 3f29770723 ("ipsec: check return value of skb_to_sgvec always")
