Fix ASSERTION(!dsl_pool_sync_context(tx->tx_pool))

Disable the normal reclaim path for the txg_sync thread.  This
ensures the thread will never enter dmu_tx_assign() which can
otherwise occur due to direct reclaim.  If this is allowed to
happen the system can deadlock.  Direct reclaim call path:

  ->shrink_icache_memory->prune_icache->dispose_list->
  clear_inode->zpl_clear_inode->zfs_inactive->dmu_tx_assign
