md: simplify code with bio_io_error
Since bio_io_error sets bi_status to BLK_STS_IOERR, and calls bio_endio, so we can use it directly. And as mentioned by Shaohua, there are also two places in raid5.c can use bio_io_error either. Signed-off-by: Guoqing Jiang <gqjiang@suse.com> Signed-off-by: Shaohua Li <shli@fb.com>
