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.
