bgpd: Change description for `[no] bgp listen limit` commands

It's quite confusing when you see this:
```
exit1-debian-9(config-router)# bgp listen
  listen  Configure BGP defaults
```

And:
```
exit1-debian-9(config-router)# no bgp listen
  listen  unset maximum number of BGP Dynamic Neighbors that can be created
```
