block: pass struct request instead of struct blk_issue_stat to wbt
issue_stat is going to go away, so first make writeback throttling take the containing request, update the internal wbt helpers accordingly, and change rwb->sync_cookie to be the request pointer instead of the issue_stat pointer. No functional change. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
