Stephen Barber 58df38b615 devices: net: add control queue for enabling/disabling offloads 
Add a control queue for virtio_net, and implement the command to set
available networking offloads.

Set offloads initially when acking features from the guest. We previously set
offloads on unconditionally.

Add TUNSETOFFLOAD to the allowed ioctls for virtio_net.

BUG=chromium:1031413
TEST=boot 5.4 guest, check vmtap offloads enabled with ethtool
TEST=enable ip_forward in guest, check vmtap offloads disabled with ethtool
