use bio_endio instead of a call to bi_end_io
Neil Brown [Fri, 27 Jun 2008 22:31:20 +0000 (08:31 +1000)]
Turn calls to bi->bi_end_io() into bio_endio(). Apparently bio_endio does
exactly the same error processing as is hardcoded at these places.

bio_endio() avoids recursion (or will soon), so it should be used.
