KVM: PPC: Explicitly require struct page memory for Ultravisor sharing
Explicitly require "struct page" memory when sharing memory between
guest and host via an Ultravisor. Given the number of pfn_to_page()
calls in the code, it's safe to assume that KVM already requires that the
pfn returned by gfn_to_pfn() is backed by struct page, i.e. this is
likely a bug fix, not a reduction in KVM capabilities.
Switching to gfn_to_page() will eventually allow removing gfn_to_pfn()
and kvm_pfn_to_refcounted_page().
