Fix memory allocation updates and add more debug

Previously, we were assigning memalloc/memprov/vcpualloc during an
earlier phase using the main d_domain list. I'm not sure exactly why,
but this was throwing off stats after a fence. Instead, set these values
later on while parsing the actually-active VMs.
