block: fix missing blkcg_bio_issue_init

The commit 513616843d ("block: remove superfluous calls to
blkcg_bio_issue_init") has removed blkcg_bio_issue_init from
__bio_clone since submit_bio will override ->bi_issue.
However, __blk_queue_split is called after blkcg_bio_issue_init
(see blk_mq_submit_bio) in submit_bio. In this case, the
->bi_issue is 0. Fix it.
