KVM: Provide refcounted page as output field in struct kvm_follow_pfn
Add kvm_follow_pfn.refcounted_page as an output for the "to pfn" APIs to
"return" the struct page that is associated with the returned pfn (if KVM
acquired a reference to the page). This will eventually allow removing
KVM's hacky kvm_pfn_to_refcounted_page() code, which is error prone and
can't detect pfns that are valid, but aren't (currently) refcounted.
