  SVN rev 216084 on 2010-11-30 21:04:05Z by trasz
  
  Don't panic when we read an empty ACL from ZFS.  Apparently this may happen
  with filesystems created under MacOS X ZFS port.  This is kind of filesystem
  corruption (we don't allow for setting empty ACLs), so make acl_get_file(3)
  and related syscalls fail with EINVAL in that case.  In theory, we could
  return empty ACL to userland, but I'm afraid this would break some code.
