Fix some TCP fast open issues.

The following issues are fixed:
* Whenever a TCP server with TCP fast open enabled, calls accept(),
  recv(), send(), and close() before the TCP-ACK segment has been received,
  the TCP connection is just dropped and the reception of the TCP-ACK
  segment triggers the sending of a TCP-RST segment.
* Whenever a TCP server with TCP fast open enabled, calls accept(), recv(),
  send(), send(), and close() before the TCP-ACK segment has been received,
  the first byte provided in the second send call is not transferred.
* Whenever a TCP client with TCP fast open enabled calls sendto() followed
  by close() the TCP connection is just dropped.
