vdpa_sim: not reset state in vdpasim_queue_ready
[ Upstream commit 0e84f918fac8ae61dcb790534fad5e3555ca2930 ]
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.
Fixes: 2c53d0f64c06 ("vdpasim: vDPA device simulator")
