Michael Brown 859664ea2a [tcp] Update window even if ACK does not acknowledge new data 
iPXE currently ignores ACKs which do not acknowledge any new data.
(In particular, it does not stop the retransmission timer; this is
done to prevent an immediate retransmission if a duplicate ACK is
received while the transmit queue is non-empty.)

If a peer provides a window size of zero and later sends a duplicate
ACK to update the window size, this update will therefore be ignored
and iPXE will never be able to transmit data.

Fix by updating the window size even for ACKs which do not acknowledge
new data.
