mm/migrate.c: attach_page_private already does the get_page

Just finished bisecting mmotm, to find why a test which used to take
four minutes now took more than an hour: the __buffer_migrate_page()
cleanup left behind a get_page() which attach_page_private() now does.

Fixes: cd0f3715 ("mm/migrate.c: call detach_page_private to cleanup code")
