[PATCH 07/22] mm: page allocator: Do not lookup the pageblock migratetype during allocation

The pageblock migrate type is checked during allocation in case it's CMA
but using get_freepage_migratetype() should be sufficient as the
magazines would have been drained prior to a CMA allocation attempt.
