writeback: expose the bdi_wq workqueue
There are cases where userland wants to tweak the priority and
affinity of writeback flushers. Expose bdi_wq to userland by setting
WQ_SYSFS. It appears under /sys/bus/workqueue/devices/writeback/ and
allows adjusting maximum concurrency level, cpumask and nice level.
