KVM: Use NULL for struct page pointer to indicate mremapped memory
Drop yet another unnecessary magic page value from KVM, as there's zero
reason to use a poisoned pointer to indicate "no page". If KVM uses a
NULL page pointer, the kernel will explode just as quickly as if KVM uses
a poisoned pointer. Never mind the fact that such usage would be a
blatant and egregious KVM bug.
