Tejun Heo bf52b1ac6a async: Use a dedicated unbound workqueue with raised min_active 
Async can schedule a number of interdependent work items. However, since
5797b1c189 ("workqueue: Implement system-wide nr_active enforcement for
unbound workqueues"), unbound workqueues have separate min_active which sets
the number of interdependent work items that can be handled. This default
value is 8 which isn't sufficient for async and can lead to stalls during
resume from suspend in some cases.

Let's use a dedicated unbound workqueue with raised min_active.
