[PATCH] as-iosched: remove state assertion in as_add_request()

Kill the arq->state poison statement in as_add_request(), it can trigger
for perfectly valid code that just reuses a request after io completion
instead of freeing it and allocating a new one. We probably should
introduce a blk_init_request() to start from scratch, but for now just
kill it as we will be removing the as specific poisoning soon.
