QoS policy with minimum bandwidth rules can be assigned to a VXLAN network if the network doesn't have any ports

[Rodolfo Alonso]

Description of problem:
Minimum bandwidth QoS rule is only applicable for the network which is backed by physical networks,
thus it should be rejected for vxlan networks, which is not associated with specific physical networks.

This is enforced in api level when a network has any port, but is NOT enforced properly if a network has no ports.

How reproducible:
Always

Steps to Reproduce:
1. Deploy overcloud with ml2+ovs
2. Create a QoS policy and add minimum baidwidth QoS rules to it
3. Create a vxlan network
4. Set the qos policy (2) on the netwokr (3)

Actual results:
Updating network policy is not rejected

Expected results:
Updating network policy is rejected
