[TCP]: Keep state in Disorder also if only lost_out > 0
This happens rather infrequently and is only possible during FRTO. We must not allow TCP to slip to Open state because tcp_fastretrans_alert might then not be called on it's time when FRTO has exited. This become a problem when left_out got removed and was replaced by just sacked_out. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
