ice: Fix added in VSI supported nodes calc
VSI supported nodes are calculated in order to add the VSI parent or intermediate nodes to the scheduler tree. If one of the node in below layers (from VSI layer) has space to add the new VSI or intermediate node above that layer then it's not required to continue the calculation further for below layers.
