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 field in core vhost code.
As the next step, cleanup vhost scsi code as well.
