With the new FD structure the async commands do not need to hold any references while running. The existing mlx5_cmd_exec_cb() and mlx5_cmd_cleanup_async_ctx() provide enough synchronization to ensure that all outstanding commands are completed before the uobject can be destructed. Remove the now confusing get_file() and the type erasure of the devx_async_cmd_event_file.
