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. Signed-off-by: Trung Tran<trung.tran@ettus.com>
