isisd: Fix the PQ space computation error in TI-LFA

When there are pseudo-nodes on the device, during TI-LFA calculation of PQ space, even if this IS vertex is not originally a P/Q node, it might be calculated as a P/Q node due to the presence of pseudo-nodes, causing this IS vertex to become a P/Q node.
