There is no need to unpin the added page when adding it to the bio fails
as that is done by the loop below. Instead we want to unpin it when adding
a single page to the bio more than once as bio_release_pages will only
unpin it once.
Fixes: d1916c86cc ("block: move same page handling from __bio_add_pc_page to the callers")
