John Baldwin f933f02094 - Minimize the amount of duplicated code for the PREEMPTION #ifdef, it now

only covers about 3-4 lines.
- Don't lower the IPL while we are on the interrupt stack.  Instead, save
  the raised IPL and change the saved IPL in sched_lock to IPL_0 before
  calling mi_switch().  When we are resumed, restore the saved IPL in
  sched_lock to the saved raised IPL so that when we release sched_lock
  we won't lower the IPL.  Without this, we would get nested interrupts
  that would overflow the kernel stack.
