mm/page_alloc: simplify how many pages are selected per pcp list during bulk free
free_pcppages_bulk() selects pages to free by round-robining between
lists. Originally this was to evenly shrink pages by migratetype but
uneven freeing is inevitable due to high pages. Simplify list selection
by starting with a list that definitely has pages on it in
free_unref_page_commit() and for drain, it does not matter where
draining starts as all pages are removed.
