Given how zfs_getattr() is implemented, zfs_getattr_fast() (used by
->getattr() of zpl inodes) also needs to consider an additional link
count if "snapdir" property is set to "visible".
Without this, # of directories in root inode of each dataset doesn't
match the link count when snapdir is visible.
