Fixed by adapting tcp_do_output_nagle().

Nagle can inhibit sending a segment although no more segments can be enqueued (due to snd_buf/snd_queuelen limitations).

This should be prevented by TF_NAGLEMEMERR, but that seems to not have worked in the FreeRTOS tests (see lwip-users list of mid-september '11 "Delayed Ack causing problems? Where to call tcp_nagle_disable()?").
