Fix typo in sys port range calculation

Summary:
This is to support Voq Scale tests to work on devices with more than one NPU (Janga).

Instead of creating dsfNodes/sys port range starting at the 2nd DSF node, compute those based on the current dsfNode struct (which will contain two nodes for Janga).

Fix the typo of using current dsfNode size instead of numCores.
