write_riemann plugin: Receive acknowledge message when using TCP.

Not receiving an acknowledge message when communicating with riemann over TCP
will cause the riemann instance to eventually hang for extended periods of time
because of resource exhaustion.

Took the time to reaorganize the riemann_send function to simplify locking.
