stats: fix collector updates of symlinks
A node name is not bound to a node index. For example, if an interface
is deleted and re-added, the indexes of its nodes "<itfc_name>-tx"
and "<itfc_name>-output" may change. Thus, when the collector updates
the nodes stats, it should first delete all the symlinks for nodes that
have changed their names before adding new symlinks. Otherwise, it
could attempt to add already existing symlinks or delete valid ones.
Example of a series of command that triggers a crash in the assert
`ASSERT (node_data[i].symlinks[j] != CLIB_U32_MAX);`:
```
create loopback interface
create loopback interface
```
Wait for the nodes stats to update, then:
```
delete loopback interface intfc loop0
delete loopback interface intfc loop1
create loopback interface
create loopback interface
```
