New subject: [libvirt] [PATCH 1/3] qemuDomainGetResctrlMonData: Don't leak @caps
The capabilities object must be unrefed when no longer needed.
use VIR_AUTOUNREF() for that.

New subject: [libvirt] [PATCH 2/3] qemuDomainGetResctrlMonData: Dereference resctrl monitor iff not NULL
If the host doesn't have resctrl then the monitor is going to be
NULL and we must avoid dereferencing it.

This way it is obvious when adding a new resource control type
that stats helper func needs to be updated too.
