[PATCH 2/2] accel/habanalabs: Replace create_singlethread_workqueue with alloc_ordered_workqueue

[George Karagounis <taterraster@gmail.com>]

create_singlethread_workqueue() is deprecated. Replace it with

alloc_ordered_workqueue() for the command, event, and reset

workqueues.

Use the %s format string specifier to satisfy the API

requirements for variable workqueue names. WQ_MEM_RECLAIM is

added to ensure hardware events are processed under memory

pressure.
