Xin Long 79272fc2c1 l2tp: fix a sock refcnt leak in l2tp_tunnel_register ... [ Upstream commit f8504f4ca0a0e9f84546ef86e00b24d2ea9a0bd2 ] This issue happens when trying to add an existent tunnel. It doesn't call sock_put() before returning -EEXIST to release the sock refcnt that was held by calling sock_hold() before the existence check. This patch is to fix it by holding the sock after doing the existence check.
