The current command UBLK_CMD_DEL_DEV won't return until the device is released, this way looks more reliable, but makes userspace more difficult to implement, especially about orders: unmap command buffer(which holds one ublkc reference), ublkc close, io_uring_file_unregister, ublkb close. Add UBLK_CMD_DEL_DEV_ASYNC so that device deletion won't wait release, then userspace needn't worry about the above order. Actually both loop and nbd is deleted in this async way.
