pbrd: fix crash with match command

Browse Source 
Crash with empty `ip-protocol`:
```
anlan(config-pbr-map)# match ip-protocol
vtysh: error reading from pbrd: Resource temporarily unavailable (11)Warning: closing connection to pbrd because of an I/O error!
```

So, give warning for empty `ip-protocol`.
