UPSTREAM: mm: migrate LRU_REFS_MASK bits in folio_migrate_flags

Bits of LRU_REFS_MASK are not inherited during migration which lead to new
folio start from tier0 when MGLRU enabled.  Try to bring as much bits of
folio->flags as possible since compaction and alloc_contig_range which
introduce migration do happen at times.
