T5941: Migration QoS delete orphaned interface traffic-policy
We can get an orphaned interface traffic-policy when the traffic-policy name is removed from the interface, but the node `trffic-policy` is still attached to the interface For exmaple we have orphaned node traffic-policy on an interface: ``` set interfaces bonding bond0 vif 995 traffic-policy ``` This causes of incorrect migration and we do not see VLANs on the bonding interface after update. Delete traffic-policy from all interfaces if traffic-policy does not exist (cherry picked from commit ca43e517408168ad1f12a3e5bc6f2d97f510faee)
