mm: consider CMA pages in watermark check for NUMA balancing target node

Currently in migrate_balanced_pgdat(), ALLOC_CMA flag is not passed when
checking watermark on the migration target node.  This does not match the
gfp in alloc_misplaced_dst_folio() which allows allocation from CMA.

This causes promotion failures when there are a lot of available CMA
memory in the system.

Therefore, we change the alloc_flags passed to zone_watermark_ok() in
migrate_balanced_pgdat().
