Alexander Motin 04d4df89f4 Avoid extra taskq_dispatch() calls by DMU ... DMU sync code calls taskq_dispatch() for each sublist of os_dirty_dnodes and os_synced_dnodes. Since the number of sublists by default is equal to number of CPUs, it will dispatch equal, potentially large, number of tasks, waking up many CPUs to handle them, even if only one or few of sublists actually have any work to do. This change adds check for empty sublists to avoid this.
