  MFC r234385:
  
  Fix bug where NFSv4 ACL enforcement code wouldn't unconditionally
  allow the owner to read and write ACL and file attributes when there
  was no entry with subject matching the owner.  In other words,
  'getfacl meh' shouldn't fail for the owner if the ACL looks like this:
  
  # file: meh
  # owner: trasz
  # group: wheel
           user:root:------a-------:------:allow
