Subject: [PATCH] net: pktgen: kill the "Wait for kthread_stop" code in
 pktgen_thread_worker()

pktgen_thread_worker() doesn't need to wait for kthread_stop(), it
can simply exit. Just pktgen_create_thread() and pg_net_exit() should
do get_task_struct()/put_task_struct(). kthread_stop(dead_thread) is
fine.
