Eli Cohen 6ccccc03f8 vdpa/mlx5: Clear vq ready indication upon device reset
[ Upstream commit e3aadf2e1614174dc81d52cbb9dabb77913b11c6 ]

After device reset, the virtqueues are not ready so clear the ready
field.

Failing to do so can result in virtio_vdpa failing to load if the device
was previously used by vhost_vdpa and the old values are ready.
virtio_vdpa expects to find VQs in "not ready" state.
