Send MAC updates to ODL for SRIOV PFs
Send MAC updates to ODL for SRIOV PFs

When the MAC on a port changes, as is the case for attaching
VM to SRIOV Physical Function(PF), ODL was not being informed.

This change removes the MAC filter on ODL port updates, so
that ODL will be informed if/when MAC changes for a port.
