From: Hou Tao <houtao1@xxxxxxxxxx> bio->bi_iter.bi_sector has already been initialized when initialize the integrity seed in dm_crypt_integrity_io_alloc(). There is no need to calculate it again. Therefore, use the helper bip_set_seed() to initialize the seed and pass bi_iter.bi_sector to it instead.
