Michael S. Tsirkin 62cee1a28a virtio: set low features early on load 
virtio migrates the low 32 feature bits twice, the first copy is there
for compatibility but ever since
019a3edbb25f1571e876f8af1ce4c55412939e5d: ("virtio: make features 64bit
wide") it's ignored on load. This is wrong since virtio_net_load tests
self announcement and guest offloads before the second copy including
high feature bits is loaded.  This means that self announcement, control
vq and guest offloads are all broken after migration.

Fix it up by loading low feature bits: somewhat ugly since high and low
bits become out of sync temporarily, but seems unavoidable for
compatibility.  The right thing to do for new features is probably to
test the host features, anyway.
