Move call of delete_from_page_cache() and page->mapping check out of
truncate_complete_page() into the single caller - truncate_inode_page().
Also move page_mapped() check into truncate_complete_page().  That way
it will be easier to batch operations.

Also rename truncate_complete_page() to truncate_cleanup_page().
