UBI: Dispatch update notification if the volume is updated
The UBI_IOCVOLUP ioctl is used to start an update and also to truncate a volume. In the first case, a "volume updated" notification is dispatched when the update is done. This commit adds the "volume updated" notification to be also sent when the volume is truncated. This is required for UBI block and gluebi to get notified about the new volume size.
