mm: compaction: do not compact pgdat for order-0
If kswapd was reclaiming for a high order and resets it to 0 due to
fragmentation it will still call compact_pgdat. For the most part, this
will fail a compaction_suitable() test and not compact but it is
unnecessarily sloppy. It could be fixed in the caller but fix it in the
API instead.
