Eli Cohen ad6dc1daaf vdpa/mlx5: Avoid processing works if workqueue was destroyed ... If mlx5_vdpa gets unloaded while a VM is running, the workqueue will be destroyed. However, vhost might still have reference to the kick function and might attempt to push new works. This could lead to null pointer dereference. To fix this, set mvdev->wq to NULL just before destroying and verify that the workqueue is not NULL in mlx5_vdpa_kick_vq before attempting to push a new work.
