mm: vmscan: rework move_pages_to_lru()

In a later patch, we will reparent the LRU pages.  The pages moved to
appropriate LRU list can be reparented during the process of the
move_pages_to_lru().  So holding a lruvec lock by the caller is wrong, we
should use the more general interface of folio_lruvec_relock_irq() to
acquire the correct lruvec lock.
