mm: remove irqsave/restore locking from contexts with irqs enabled
The page cache deletion paths all have interrupts enabled, so no need to use irqsafe/irqrestore locking variants. They used to have irqs disabled by the memcg lock added in commit c4843a75 ("memcg: add per cgroup dirty page accounting"), but that has since been replaced by memcg taking the page lock instead, commit 0a31bc97 ("mm: memcontrol: rewrite uncharge AP").
