drm/vboxvideo: Don't set struct drm_driver.lastclose

Don't set struct drm_driver.lastclose. It's used to restore the
fbdev console. But as vboxvideo uses generic fbdev emulation, the
console is being restored by the DRM client helpers already. See
the call to drm_client_dev_restore() in drm_lastclose().
