[PATCH resend 2/2] mm,memory_hotplug: Drop redundant hugepage_migration_supported check

[Oscar Salvador]

has_unmovable_pages() does alreay check whether the hugetlb page supports
migration, so all non-migrateable hugetlb pages should have been caught there.
Let us drop the check from scan_movable_pages() as is redundant.
