Correct 32on64 handling of VCPUOP_register_runstate_memory_area.  We
were copying too many bytes from the guest so the test for
area.addr.h.c != area.addr.p was failing.

Added a WARN_ON to the kernel to catch this case. It would be a BUG_ON
but this would break the new kernel on older hypervisors and the only
real problem is that stolen time is not updated, which we can live
with.
