[PATCH 17/20 v1] [SCSI] mpt3sas: Use alloc_ordered_workqueue() API instead of create_singlethread_workqueue() API

From: Sreekanth Reddy
Date: Tue Jun 16 2015 - 01:37:34 EST

Created a thread using alloc_ordered_workqueue() API in order to process
the works from firmware Work-queue sequentially instead of
create_singlethread_workqueue() API.

Changes in v1:
No need to check for backport compatibility in the upstream kernel.
so removing the else section where driver use
create_singlethread_workqueue() API if alloc_ordered_workqueue() API is
not defined, This else section is not required since in the latest upstream
kernel this alloc_ordered_workqueue() API is always defined.
