kernel - Add vm.swapcache.maxscan

* Add vm.swapcache.maxscan as a separate counter from vm.swapcache.maxlaunder.

* Defaults to 4x maxlaunder.

* Should hopefully fix another cpu hogging issue that was noticed on
  avalon when most VM pages wind up being cached in the swapcache
  but still get cycled in the PQ_INACTIVE VM page queue due to apache
  activity.
