When converting a gfn to a pfn, we call gfn_to_pfn_prot, which returns various kinds of error values. It turns out that is_error_pfn() only returns true when the gfn was found in a memory slot and could somehow not be used, but it does not return true if the gfn does not belong to any memory slot. Change use to is_error_noslot_pfn() which covers both cases. Note: Since we already check for kvm_is_error_hva(hva) explicitly in the caller of this function while holding the kvm->srcu lock protecting the memory slots, this should never be a problem, but nevertheless this change is warranted as it shows the intention of the code.
