block: fix missing blkcg_bio_issue_init
The commit513616843d
("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. Fixes:513616843d
