qed: Update TCP silly-window-syndrome timeout for iwarp, scsi
Update TCP silly-window-syndrome timeout, for the cases where
initiator's small TCP window size prevents FW from transmitting
packets on the connection. Timeout causes FW to retransmit
window probes if needed, preventing I/O stall if initiator ignores
first window probe.
