Public bug reported:

1) create a network with qos policy (with min_bw rule)
2) create a port in that network without explicit qos policy (so the port inherits the policy from the network)
3) boot a server with that port
4) update the qos policy on the network

Expected either:
A)
* qos policy change is accepted
* the port resource request is updated according to the new qos policy
* the placement allocation is updated according to the new qos policy

B)
* qos policy update is rejected

Actual:
* qos policy change is accepted -> OK as in A)
* the port resource request is updated according to the new qos policy -> OK as in A)
* the placement allocation is _not_ updated -> NOT OK in A)
