  Log:
  ndis will signal the kthread to exit and then sleep on the proc pointer to
  be woken up by kthread_exit. This is racey and in some cases the kthread will
  exit before ndis gets around to sleep so it will be stuck indefinitely. This
  change reuses the kq_exit variable to indicate that the thread has gone and
  will loop on tsleep with a timeout waiting for it. If the kthread has already
  exited then it will not sleep at all.
