af_packet: reflect admin device state on host
Setting the interface state in VPP on an af_packet device, was not being reflected on the host. This implied the user had to set the device state in VPP and then on the host, in order to put the interface into an 'up' state. This changes makes the device state consisent in VPP and the host.
