Eli Cohen b34dbeb2b0 vdpa/mlx5: Initialize CVQ vringh only once
[ Upstream commit ace9252446 ]

Currently, CVQ vringh is initialized inside setup_virtqueues() which is
called every time a memory update is done. This is undesirable since it
resets all the context of the vring, including the available and used
indices.

Move the initialization to mlx5_vdpa_set_status() when
VIRTIO_CONFIG_S_DRIVER_OK is set.
