Btrfs: do not reset bio->bi_ops while writing bio
flush_epd_write_bio() sets bio->bi_opf by itself to honor REQ_SYNC, but it's not needed at all since bio->bi_opf has set up properly in both __extent_writepage() and write_one_eb(), and in the case of write_one_eb(), it also sets REQ_META, which we will lose in flush_epd_write_bio(). This remove this unnecessary bio->bi_opf setting. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
