Specify interface when assigning primary MAC address

MAC address objects are not necessarily unique in netbox, so when assigning the
primary_interface_field match on the parent object to ensure uniqueness
(example usecase: when using virtual VLAN interfaces on a physical interface,
the children interface may use the same MAC. Then this update fails with an
HTTP 400 because there are multiple netbox MAC address objects with the same
MAC)
