block: remove the checking for NULL queue in blk_put_request
Some uses blk_put_request asymmetrically, that is, they uses it with requests that not allocated by blk_get_request. As a result, blk_put_request has a hack to catch a NULL request_queue. Now such callers are fixed (they use blk_get_request properly). So we can safely remove the hack in blk_put_request.
