[Beignet] [PATCH] Fix instruction scheduler ScheduleDAGNode

[Homer Hsing]

When we add dependency for ScheduleDAGNode, we use
ScheduleDAGNode(node1)->children.push_back(node0) to express
node0 depends on node1.

To check this dependency, we should check whether node0 is inside
node1->children.

Original code checks whether node1 is inside node0->children.

So we fix this.
