ide-atapi: don't abuse rq->buffer
Impact: rq->buffer usage cleanup ide-atapi uses rq->buffer as private opaque value for internal special requests. rq->special isn't used for these cases (the only case where rq->special is used is for ide-tape rw requests). Use rq->special instead. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Jens Axboe <axboe@kernel.dk>
