Title: Pipe.m_inboundPipe already null

In one of my tests, I provoked an avoidable, uncaught NullReferenceException on a
dealer socket that was attempting to deal with an
unexpectedly-terminated remote router socket.
Checking whether or not the m_inboundPipe is already deallocated takes
care of that.
