Don't adjust the userspace address in the gfn=>pfn cache by the page offset from the gpa. KVM should never use the user address directly, and all KVM operations that translate a user address to something else require the user address to be page aligned. Ignoring the offset will allow the cache to reuse a gfn=>hva translation in the unlikely event that the page offset of the gpa changes, but the gfn does not.
