dm: dm-zoned: use __bio_add_page for adding single metadata page

Browse Source 
dm-zoned uses bio_add_page() for adding a single page to a freshly created
metadata bio.

Use __bio_add_page() instead as adding a single page to a new bio is
always guaranteed to succeed.

This brings us a step closer to marking bio_add_page() __must_check
