[PATCH] accel: habanalabs: use alloc_ordered_workqueue()

[Shi Hao]

Replace the deprecated create_singlethread_workqueue() functions with
alloc_ordered_workqueue() since it aligns with current workqueue API
modernization efforts. The conversion is safe since destroy_workqueue()
is used for cleanup in both cases.

No functional changes intended.

Applied to accel/habanalabs-next, thanks.
