  SVN rev 184599 on 2008-11-03 20:00:35Z by attilio
  
  Remove the mnt_holdcnt and mnt_holdcntwaiters because they are useless.
  Really, the concept of holdcnt in the struct mount is rappresented by
  the mnt_ref (which prevents the type-stable structure from being
  "recycled) handled through vfs_ref() and vfs_rel().
  On this optic, switch the holdcnt acquisition into an emulated vfs_ref()
  (and subsequent release into vfs_rel()).
