tcp: fix FIONREAD/SIOCINQ
[ Upstream commit a3374c42aa5f7237e87ff3b0622018636b0c847e ]
tcp_ioctl() tries to take into account if tcp socket received a FIN
to report correct number bytes in receive queue.
But its flaky because if the application ate the last skb,
we return 1 instead of 0.
Correct way to detect that FIN was received is to test SOCK_DONE.
