KVM: x86: use u64_to_user_ptr()
There is no danger to the kernel if 32-bit userspace provides a 64-bit
value that has the high bits set, but for whatever reason happens to
resolve to an address that has something mapped there. KVM uses the
checked version of get_user() and put_user(), so any faults are caught
properly.
