[PATCH] Optimize free_one_page

Free one_page currently adds the page to a fake list and calls
free_page_bulk.  Fee_page_bulk takes it off again and then calles
__free_one_page.

Make free_one_page go directly to __free_one_page.  Saves list on / off and
a temporary list in free_one_page for higher ordered pages.
