Mikulas Patocka 718822c1c1 dm delay: fix a possible deadlock due to shared workqueue 
The dm-delay target uses a shared workqueue for multiple instances.  This
can cause deadlock if two or more dm-delay targets are stacked on the top
of each other.

This patch changes dm-delay to use a per-instance workqueue.
