Since oct->props[i].netdev is still\nNULL at this point, the cleanup function liquidio_destroy_nic_device()\nwill fail to find and free the netdev, resulting in a memory leak.\n\nFix this by initializing oct->props[i].netdev before calling the queue\nsetup functions. This ensures that the netdev is properly accessible for\ncleanup in case of errors.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review."
