tcp: clear tp->data_segs{in|out} in tcp_disconnect()
[ Upstream commit db7ffee6f3eb3683cdcaeddecc0a630a14546fe3 ]
tp->data_segs_in and tp->data_segs_out need to be cleared
in tcp_disconnect().
tcp_disconnect() is rarely used, but it is worth fixing it.
Fixes: a44d6eacdaf5 ("tcp: Add RFC4898 tcpEStatsPerfDataSegsOut/In")
