Andy Ross aed8288196 kernel/sched: Handle aboring _current correctly in SMP 
In SMP, _current is not "queued".  (The run queue only stores
unscheduled threads because we can't rely on the head of the list
being _current).  We weren't updating the cache choice, which would
flag swap_ok, so calling k_thread_abort(_current) (for example, when a
thread exits from its entry function) would try to switch back into
the thread and then run off the end of the function.

Amusingly this was more benign than you'd think.  Stumbled on it by
accident.
