ospfd: fix memory leaks in summarization

To reproduce the issue:
1. Create summary-address: `summary-address 1.1.1.0/24`.
2. Try to delete it with the wrong tag: `no summary-address 1.1.1.0/24 tag 1`.
   Each time this command is executed, route_node_lookup is called which
   locks route node one more time. As the tag is wrong, the function
   return immediately without unlock.
3. Finally delete the summary-address: `no summary-address 1.1.1.0/24`.

The route node won't be deleted.
