[ Upstream commit 470acf55a0 ]
There are two cases which causes refcnt leak.
1. When nf_ct_timeout_ext_add failed in xt_ct_set_timeout, it should
free the timeout refcnt.
Now goto the err_put_timeout error handler instead of going ahead.
2. When the time policy is not found, we should call module_put.
Otherwise, the related cthelper module cannot be removed anymore.
It is easy to reproduce by typing the following command:
# iptables -t raw -A OUTPUT -p tcp -j CT --helper ftp --timeout xxx
