net/mlx5_core/health: Remove deprecated create_singlethread_workqueue
The workqueue health->wq was used as per device private health thread.
This was done to perform delayed work.
The workqueue has a single workitem(&health->work) and
hence doesn't require ordering. It is involved in handling the health of
the device and is not being used on a memory reclaim path.
Hence, the singlethreaded workqueue has been replaced with the use of
system_wq.
Work item has been flushed in mlx5_health_cleanup() to ensure that
there are no pending tasks while disconnecting the driver.
