isisd: fix the display topology command

The unconfigured flexible algorithm should not be displayed.

Before:
```
anlan# show isis topology algorithm
Area A: Algorithm 128

Area A:Area A:Area A:Area A:Area A:Area A:Area A:Area A:Area A:Area ...
......
anlan#
```

After:
```
anlan# show isis topology algorithm
Area A: Algorithm 128

anlan#
```
