Bowen Wang 1fa6a43a40 openamp: optimize virtqueue_notification() called condition ...

1. call virtqueue_notification() only when buffer exist to avoid unnecessary
calls to virtqueue callback.

2. call virtqueue_notification() only when vq != NULL, because
rproc_virtio_notified() may be called when the virtqueues is not created:
virtqueue created in the virtio/vhost driver but the virtio devices
has been added to the remoteproc virtio devices list after the remoteproc
transport layer create the virtio devices.
