David Woodhouse f18a02b458 KVM: Update gfn_to_pfn_cache khva when it moves within the same page ...

commit 8332f0ed4f upstream.

In the case where a GPC is refreshed to a different location within the
same page, we didn't bother to update it. Mostly we don't need to, but
since the ->khva field also includes the offset within the page, that
does have to be updated.

Fixes: 3ba2c95ea1 ("KVM: Do not incorporate page offset into gfn=>pfn cache user address")
