  Log:
  HAMMER 45/Many: Stabilization pass, undo sequencing.
  
  * The flusher was improperly requesting a reflush on buffers.  The flush
    request was being defered for any buffers with active front-end references
    and then wound up being flushed by the front-end, breaking ordering
    requirements.
  
    Remove the reflush flag entirely.  This fixes numerous crash recovery
    cases.
  
  * Add a missing unlock in the reblocking ioctl code which was responsible
    for a number of process lockups.
  
  * Enhance the undo recovery kprintf.
  
  * Validate the CRC in UNDO records
