vkernel - Fix corrupt tailq (vkernel64 only)
* Properly remove an exiting thread from any tsleep queue it might be
enqueued on (due to tsleep_interlock() use cases) prior to exiting.
* Fixes tailq corruption which can occur with threaded programs.
* Fix is only applicable to vkernel64. All other platforms already
properly remove the thread.
* Assert that an exiting thread has been removed from any sleep queue
before freeing it in kern_exit.c to catch any future cases.
