kernel - Performance tuning (4)

* Fix another bug in the new buf/bio code.  The flushing state can
  inadvertently become active and cause an endless loop due to a
  64-bit optimization (when BKVASIZE == MAXBSIZE) which is not properly
  conditionalized.

* Fix the endless loop.

* Add some debug variables and a sysctl to control it (temporary).
