l2tp: avoid use-after-free caused by l2tp_ip_backlog_recv
commit 51fb60eb162ab84c5edf2ae9c63cf0b878e5547e upstream.
l2tp_ip_backlog_recv may not return -1 if the packet gets dropped.
The return value is passed up to ip_local_deliver_finish, which treats
negative values as an IP protocol number for resubmission.
