[PATCH] net: ethernet: intel: fm10k: Remove create_workqueue

From: Bhaktipriya Shridhar
Date: Wed Jun 01 2016 - 11:40:19 EST

alloc_workqueue replaces deprecated create_workqueue().

A dedicated workqueue has been used since the workitem (viz
fm10k_service_task, which manages and runs other subtasks) is involved in
normal device operation and requires forward progress under memory

create_workqueue has been replaced with alloc_workqueue with max_active
as 0 since there is no need for throttling the number of active work

Since network devices may be used in memory reclaim path,
WQ_MEM_RECLAIM has been set to guarantee forward progress.

flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty. Hence the call to flush_workqueue() has been dropped.
