Subject: [PATCH] mm: fix wrong argument of migrate_huge_pages() in soft_offline_huge_page()

Commit a6bc32b899223a877f595ef9ddc1e89ead5072b8 ('mm: compaction: introduce
sync-light migration for use by compaction') change declaration of
migrate_pages() and migrate_huge_pages().
But, it miss changing argument of migrate_huge_pages()
in soft_offline_huge_page(). In this case, we should call with MIGRATE_SYNC.
So change it.

Additionally, there is mismatch between type of argument and function
declaration for migrate_pages(). So fix this simple case, too.
