[PATCH 27/32] reiserfs: make commit_wq use the default concurrency level

[Tejun Heo]

The maximum number of concurrent work items queued on commit_wq is
bound by the number of active journals.  Convert to alloc_workqueue()
and use the default concurrency level so that they can be processed in
parallel.

Only compile tested.  Please feel free to take it into the subsystem
tree or simply ack - I'll route it through the wq tree.

Thanks.
