mm/mm_init: simplify deferred_free_pages() migratetype init

Browse source

deferred_free_pages() open-codes two loops to initialize the pageblock
migratetype for a range of pages.

Replace them with pageblock_migratetype_init_range() to remove the
duplication and make the code clearer (Note that deferred_free_pages() may
be called from atomic context).
