zeromq: Call super class DoTerminate() after stopping thread

Browse source 
The internal ZeroMQ thread would call QueueForProcessing() thereby
accessing the onloop member. As ThreadedBackend::DoTerminate() unsets it,
this was a) reported as a data race by TSAN and b) potentially caused
missed events that were still to be queued.
