- Insert thread0 into correct thread hash link list.
- In thr_exit() and kthread_exit(), only remove thread from
  hash if it can directly exit, otherwise let exit1() do it.
- In thread_suspend_check(), fix cleanup code when thread needs
  to exit.
This change seems fixed the "Bad link elm " panic found by
Peter Holm.

Stress testing: pho
