flush_epd_write_bio() sets bio->bi_ops by itself to honor REQ_SYNC, but it's not needed at all since bio->bi_ops 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_ops setting.
