bio: add bio_endio_status

Add a bio_endio_status() helper as a shortcut for calling
bio_set_status() and bio_endio() in sequence. Use the new helper
throughout the code.

Created with Coccinelle using the following semantic patch:

@@
expression bio, status;
@@
- bio_set_status(bio, status);
- bio_endio(bio);
+ bio_endio_status(bio, status);
