zebra: fix wrong linkdown flag

Browse source 
Add this one line command to one down interface (mask is 192.168.0.0/24):
```
ip link set dev enp2s0 up;ip route add 3.3.3.3/32 via 192.168.0.1 dev enp2s0 proto kernel onlink
```

Before:
```
K>* 3.3.3.3/32 [0/0] via 192.168.0.1, enp2s0 onlink linkdown, weight 1, 00:00:02
```

After:
```
K>* 3.3.3.3/32 [0/0] via 192.168.0.1, enp2s0 onlink, weight 1, 00:00:02
```

It's only display problem, just correct this linkdown flag.
