dm delay: fix a possible deadlock due to shared workqueue
commit 718822c1c112dc99e0c72c8968ee1db9d9d910f0 upstream.
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.
