l4p/tcp: correct TCP stream establish seq/ack misordering

The calls made by tle_tcp_stream_establish for filling the snd and rcv
TCB seq/ack values assume numbers taken from a SYN/ACK. This makes the
expected ordering backwards from the perspective of the stream itself.
I.e. Data from stream's SEQ number aligns with SYN/ACK's ACK number.
