kernel - Add negative caching to cache_findmount()

* Add negative caching to cache_findmount().  It turns out that there
  are quite a few cases, particularly during poudriere, so this is
  needed to avoid dropping down into the slow mountlist scan code.

* Removes remaining bottlenecks in mount-point crossings during path
  lookups.  The mountlist_token is no longer colliding in critical
  paths.
