Normal page init path frees pages during the boot in MAX_ORDER chunks,
but deferred page init path does it in pageblock blocks.
Change deferred page init path to work in MAX_ORDER blocks.
For cases when MAX_ORDER is larger than pageblock, set migrate type to
MIGRATE_MOVABLE for all pageblocks covered by the page.
