btrfs: use btrfsic_submit_bio instead of submit_bio in write_dev_flush
Although this bio has no data attached, it will reach this condition (bio->bi_opf & REQ_PREFLUSH) and then update the flush_gen of dev_state in __btrfsic_submit_bio. So we should still submit it through integrity checker. Otherwise, the integrity checker will throw the following warning when I mount a newly created btrfs filesystem.
