[PATCH 16/17] ufs: convert ufs_get_page to read_kmap_page

Replace ufs_get_page()/ufs_get_locked_page() and ufs_put_page()/ufs_put_locked_page() using the new read_kmap_page() and put_kmapped_page() calls and their locking variants. Also, change the ufs_check_page() call to return the page's error status, and update the call sites accordingly.
