Fix two independent inconsistencies in resctrl monitor domstats
reporting. The first patch reports the actual resctrl monitor group name
instead of its internal ID. The second avoids reporting a zero cache
monitor count when no cache monitor data is available, matching the
memory bandwidth and energy collectors.

These patches were previously posted as part of the whole-process
resctrl series:

https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/QFXZZOHRSAUIUZYANHKRAXPBDQH2OSKM/

Changes since v1:
- Split the independent fixes from the whole-process feature series.
- Rebased onto current master.
- Added Christopher's Reviewed-by.
- Limited the domstats cleanup to the independent cache monitor fix.
  whole-process vCPU reporting remains in the feature series.
