i40evf: fix MAC deletion when stopping

Browse Source 
When dev_stop is called in i40evf pmd driver, queues are switched off
to stop receiving and transmitting. But the mac address of this VF
still exists in VEB switch.
To stop the traffic from VSI level, the mac address need to be removed
too. Then the bandwidth for this SRIOV VSI can be freed.
This patch fix this issue.
