xfs: convert to alloc_workqueue()
Convert from create[_singlethread]_workqueue() to alloc_workqueue(). * xfsdatad_workqueue and xfsconvertd_workqueue are identity converted. Using higher concurrency limit might be useful but given the complexity of workqueue usage in xfs, proceeding cautiously seems better. * xfs_mru_reap_wq is converted to non-ordered workqueue with max concurrency of 1 as the work items don't require any specific ordering and already have proper synchronization. It seems it was singlethreaded to save worker threads, which is no longer a concern.
