This fixes a bug in the code which allows userspace to read out the
contents of the guest's hashed page table (HPT). On the second and
subsequent passes through the HPT, when we are reporting only those
entries that have changed, we were incorrectly initializing the index
field of the header with the index of the first entry we skipped
rather than the first changed entry. This fixes it.
