mm/page_alloc: make deferred page init free pages in MAX_ORDER blocks

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.
