mm: vmscan: prepare for the refactoring the move_folios_to_lru()
Once we refactor move_folios_to_lru(), its callers will no longer have to hold the lruvec lock; For shrink_inactive_list(), shrink_active_list() and evict_folios(), IRQ disabling is only needed for __count_vm_events() and __mod_node_page_state(). To avoid using local_irq_disable() on the PREEMPT_RT kernel, let's make all callers of move_folios_to_lru() use IRQ-safed count_vm_events() and mod_node_page_state().
