T5941: Migration policy delete orphaned interface policy

We can get orphaned interface policy when the policy name was
removed from the interface but the node `policy` still attached
to the interface

For exmaple we have orphaned node policy on interface:
```
set interfaces bonding bond0 vif 995 policy
```

This causes of incorrect migration and we do not see VLANs on
the bonding interface after update.

Delete policy from all interfaces if policy does not exist
