[PATCH v12 79/84] KVM: s390: Use kvm_release_page_dirty() to unpin "struct page" memory

[Sean Christopherson]

Use kvm_release_page_dirty() when unpinning guest pages, as the pfn was
retrieved via pin_guest_page(), i.e. is guaranteed to be backed by struct
page memory.  This will allow dropping kvm_release_pfn_dirty() and
friends.
