BIOSET_NEED_RESCUER is only need on a bioset is allocations will be made inside a make_request_fn() call.
dm_io() is called from make_request_fn() context. The closest it comes is in chunk_io() in dm-snap-persistent. Here the code uses a separate thread to avoid problems. So BIOSET_NEED_RESCUER is not needed.
