SR-IOV. After migration/evacuation of an instance, its MAC is not cleaned up from the source node

--- Environment ---
MOS: 9.2+
Features: SR-IOV

--- Description ---
After migration/evacuation of an instance, its MAC is not cleaned up from the corresponding VF in the source node.

--- Steps to reproduce ---
(a sample of reproduction attempt is attached)
1) Build an environment with SR-IOV support and at least 2 compute nodes
2) Create an SR-IOV Neutron port
3) Spin up a VM instance connected to this Neutron port
4) Determine the compute node that hosts this instance
5) In this Compute node check MAC-addresses associated to VFs of the corresponding physical NIC
6) Mark this Compute node as disabled
7) Evacuate the instance to another Compute node
8) Repeat the step #5 on the same node

--- Actual result ---
The MAC-address is still associated to VF

--- Expected result ---
The MAC-address has been cleaned up
