We have two functions for adding a page to a bio, __bio_add_page() which is
used to add a single page to a freshly created bio and bio_add_page() which is
used to add a page to an existing bio.

While __bio_add_page() is expected to succeed, bio_add_page() can fail.

This series converts the callers of bio_add_page() which can easily use
__bio_add_page() to using it and checks the return of bio_add_page() for
callers that don't work on a freshly created bio.

Lastly it marks bio_add_page() as __must_check so we don't have to go again
and audit all callers.

Changes to v1:
- Removed pointless comment pointed out by Willy
- Changed commit messages pointed out by Damien
- Colledted Damien's Reviews and Acks

  btrfs: repair: use __bio_add_page for adding single page
  btrfs: raid56: use __bio_add_page to add single page

The btrfs patches added to misc-next, thanks.

Thanks but wouldn't it make more sense for Jens to pick up all of them?
The last patch in the series flips bio_add_pages() over to
__must_check and so it'll create an interdependency between the
btrfs and the block tree.
