Because truncate_inode_pages() is actively destroying the page cache for
those pages which are no longer valid for the inode in question, and
the way it does that is to remove the page from the page cache lists and
then to free the page. The reference count being destroyed by
truncate_inode_pages() is the one held by the page cache itself.
