[tcp] Update received sequence number before delivering received data
iPXE currently updates the TCP sequence number after delivering the
data to the application via xfer_deliver_iob(). If the application
responds to the received data by transmitting more data, this would
result in a stale ACK number appearing in the transmitted packet,
which potentially causes retransmissions and also gives the
undesirable appearance of violating causality (by sending a response
to a message that we claim not to have yet received).
