cxlflash: Fix to prevent workq from accessing freed memory ...
The workq can process work in parallel with a remove event, leading
to a condition where the workq handler can access freed memory.
To remedy, the workq should be terminated prior to freeing memory. Move
the termination call earlier in remove and use cancel_work_sync() instead
of flush_work() as there is not a need to process any scheduled work when
shutting down.
