dm: free io_barrier after blk_cleanup_queue call
dm_old_request_fn() has paths that access md->io_barrier. The party
destroying io_barrier should ensure that no future execution of
dm_old_request_fn() is possible. Move io_barrier destruction to below
blk_cleanup_queue() to ensure this and avoid a NULL pointer crash during
request-based DM device shutdown.
