tcp: clear tp->total_retrans in tcp_disconnect()
total_retrans needs to be cleared in tcp_disconnect(). tcp_disconnect() is rarely used, but it is worth fixing it. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: SeongJae Park <sjpark@amazon.de> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
