vhost_net: init acked_features to backend_features
commit 2e6d46d77ed328d34a94688da8371bcbe243479b (vhost: add
vhost_get_features and vhost_ack_features) removes the step that
initializes the acked_features to backend_features.
As this field is now uninitialized, vhost initialization will sometimes
fail.
To fix, initialize acked_features on each ack.
