Matthew Waters b3afd1a2fc flowcombiner: passthrough the flow return if there are no pads
What may happen is that during the course of processing a buffer,
all of the pads in a flow combiner may disappear.  In this case, we
would return NOT_LINKED.  Instead return whatever the input flow return
was.
