vdpa_sim: not reset state in vdpasim_queue_ready
vdpasim_queue_ready calls vringh_init_iotlb, which resets split indexes. But it can be called after setting a ring base with vdpasim_set_vq_state. Fix it by stashing them. They're still resetted in vdpasim_vq_reset. This was discovered and tested live migrating the vdpa_sim_net device.
