node_ctrl_base: add check valid num_input_ports
A node is not a block, it doesn't use any block definition to
populate the number of input and output ports. This is equivalent to it
have undefined number of input and output ports.
The _find_child_node function relies on node input and output port size.
When port size is not defined we should not follow the active channel;
instead, we need to greedily to find all child node.
Without this change graph_search_test will fail.
