Chandra Seetharaman bab7cfc733 [SCSI] scsi_dh: Add a single threaded workqueue for initializing paths
Before this patch set (SCSI hardware handlers), initialization of a
path was done asynchronously. Doing that requires a workqueue in each
device/hardware handler module and leads to unneccessary complication
in the device handler code, making it difficult to read the code and
follow the state diagram.

Moving that workqueue to this level makes the device handler code simpler.
Hence, the workqueue is moved to dm level.

A new workqueue is added instead of adding it to the existing workqueue
(kmpathd) for the following reasons:
	1. Device activation has to happen faster, stacking them along
	   with the other workqueue might lead to unnecessary delay
	   in the activation of the path.
	2. The effect could be felt the other way too. i.e the current
	   events that are handled by the existing workqueue might get
	   a delayed response.
