of: set TCP_NODELAY for secure channel socket

Due to Nagle, an OF message that an application sends might be not
delivered to a switch immediately. This patch disables Nagle. This has
bad effect on throughput. I think that the latency matters for any
management channel. To avoid throughput drop, we could use TCP_CORK on
Linux but it's linux specific.
