Subject: RDS: fix rds_tcp_init() error path

From: Vegard Nossum <vegard.nossum@oracle.com>

commit 3dad5424adfb346c871847d467f97dcdca64ea97 upstream.

If register_pernet_subsys() fails, we shouldn't try to call
unregister_pernet_subsys().

Fixes: 467fa15356 ("RDS-TCP: Support multiple RDS-TCP listen endpoints, one per netns.")
