i40e: Fix VF disable behavior to block all traffic

Browse source

Currently, if a VF is disabled using the
'ip link set dev $ETHX vf $VF_NUM state disable' command, the VF is still
able to receive traffic.

Fix the behavior of the 'ip link set dev $ETHX vf $VF_NUM state disable'
to completely shutdown the VF's queues making it entirely disabled and
not able to receive or send any traffic.

Modify the behavior of the 'ip link set $ETHX vf $VF_NUM state enable'
command to make a VF do reinitialization bringing the queues back up.
