drm/virtio: check return value of vgdev_output_init()

Browse Source 
The return value of vgdev_output_init(), called by
virtio_gpu_modeset_init(), is not checked. As a result, modeset
initialization continues even if an output fails to initialize.

check the return value and return the error to the caller.
