mmc: block: correct 4KB alignment check
In sectors alignment check, brq->data.blocks means sectors of the
previous mqrq since data.blocks for mqrq_cur hasn't been updated yet.
data.blocks will be updated later in mmc_blk_packed_hdr_wrq_prep or
mmc_blk_rw_rq_prep.
static int mmc_blk_issue_rw_rq(struct mmc_queue *mq, ......
......
struct mmc_blk_request *brq = &mq->mqrq_cur->brq;
