mm: remove is_migrate_highatomic()
There are 3 potential reasons for is_migrate_*() helpers:
1. They represent higher-level attributes of migratetypes, like
is_migrate_movable()
2. They are ifdef'd, like is_migrate_isolate().
3. For consistency with an is_migrate_*_page() helper, also like
is_migrate_isolate().
It looks like is_migrate_highatomic() was for case 3, but that was
removed in commit e0932b6c1f94 ("mm: page_alloc: consolidate free page
accounting").
So remove the indirection and go back to a simple comparison.
