tcp: Reset bytes_acked and bytes_received when disconnecting
[ Upstream commit e858faf556d4e14c750ba1e8852783c6f9520a0e ]
If an app is playing tricks to reuse a socket via tcp_disconnect(),
bytes_acked/received needs to be reset to 0. Otherwise tcp_info will
report the sum of the current and the old connection..
