vdpa_sim: fix vringh initialization in vdpasim_queue_ready()
[ Upstream commit 794ec498 ] When we initialize vringh, we should pass the features and the number of elements in the virtqueue negotiated with the driver, otherwise operations with vringh may fail. This was discovered in a case where the driver sets a number of elements in the virtqueue different from the value returned by .get_vq_num_max(). In vdpasim_vq_reset() is safe to initialize the vringh with default values, since the virtqueue will not be used until vdpasim_queue_ready() is called again.
