Subject: ipv6: release dst on error in ip6_dst_lookup_tail
From: Willem de Bruijn <willemb@xxxxxxxxxx>
commit 00ea1ceebe0d9f2dc1cc2b7bd575a00100c27869 upstream.
If ip6_dst_lookup_tail has acquired a dst and fails the IPv4-mapped
check, release the dst before returning an error.
Fixes: ec5e3b0a1d41 ("ipv6: Inhibit IPv4-mapped src address on the wire.")
