        src/sys/kern: kern_exit.c kern_lwp.c

Log Message:
once exit1() releases big kernel lock, the struct proc can be freed and
re-used by another cpu immediately.  in that case, lwp_exit2() will
access freed memory.  to fix this:

- remove curlwp from p_lwps in exit1() rather than letting lwp_exit2() do so.
- add assertions to ensure freed proc has no lwps.
