- Move contents of sched_add() into a sched_add_internal() function that
  takes an argument to specify if it should preempt or not.  Don't preempt
  when sched_add_internal() is called from kseq_idled() or kseq_assign()
  as in those cases we are about to call mi_switch() anyways.  Also, doing
  so during the first context switch on an AP leads to a NULL pointer deref
  because curthread is NULL.
- Reenable preemption for ULE.
