[PATCH 4/4] bio: use bio_io_error more often

[Andreas Gruenbacher]

Instead of setting bio->bi_status to BLK_STS_IOERR and calling
bio_endio(bio), use the shorthand bio_io_error(bio).

Created with Coccinelle using the following semantic patch:

@@
struct bio *bio;
@@
- bio->bi_status = BLK_STS_IOERR;
- bio_endio(bio);
+ bio_io_error(bio);
