mm/page_alloc: use get_pfnblock_migratetype to avoid extra page_to_pfn
We have get_pageblock_migratetype and get_pfnblock_migratetype to get
migratetype of page. get_pfnblock_migratetype accepts both page and pfn
from caller while get_pageblock_migratetype only accept page and get pfn
with page_to_pfn from page.
In case we already record pfn of page, we can simply call
get_pfnblock_migratetype to avoid a page_to_pfn.
