Subject: [PATCH 06/33] tipc: fix memory leak in tipc_accept_from_sock()

From: Jon Maloy <[email-masked]>
Date: Mon, 4 Dec 2017 22:00:20 +0100

[ Upstream commit a7d5f107b4978e08eeab599ee7449af34d034053 ]

When the function tipc_accept_from_sock() fails to create an instance of
struct tipc_subscriber it omits to free the already created instance of
struct tipc_conn instance before it returns.

We fix that with this commit.
