mm: fix tracing in free_pcppages_bulk()
page->private gets re-used in __free_one_page() to store page order
(so trace_mm_page_pcpu_drain() may print order instead of migratetype)
thus migratetype value must be cached locally.
Fixes regression introduced in commit a7016235a61d ("mm: fix migratetype
bug which slowed swapping"). This caused incorrect data to be attached
to the mm_page_pcpu_drain trace event.
