zonefs: use __bio_add_page for adding single page to bio
The zonefs superblock reading code uses bio_add_page() to add a page to a
newly created bio. bio_add_page() can fail, but the return value is
never checked.
Use __bio_add_page() as adding a single page to a newly created bio is
guaranteed to succeed.
This brings us a step closer to marking bio_add_page() as __must_check.
