kernel - Fix bug in the emergency interrupt polling thread

* This thread is only active when kern.emergency_intr_enable is non-zero

* Get the next intr handler before processing the current one, since the
  act of processing the current handler may remove it.

* In the emergency interrupt polling thread do not stall if we cannot get
  the serializer for the interrupt.  just skip the handler and we'll try
  again next time.
