block: remove the anticipatory IO scheduler
AS is mostly a subset of CFQ, so there's little point in still providing this separate IO scheduler. Hopefully at some point we can get down to one single IO scheduler again, at least this brings us closer by having only one intelligent IO scheduler. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
