When user doesn't have read access on one of the domains he requested, the for loop could exit abruptly or continue and override pointer which pointed to locked object. This patch fixed two issues at once. One is that domflags might have had QEMU_DOMAIN_STATS_HAVE_JOB even when there was no job started (this is fixed by doing domflags |= QEMU_DOMAIN_STATS_HAVE_JOB only when the job was acquired and cleaning domflags on every start of the loop. Second one is that the domain is kept locked when virConnectGetAllDomainStatsCheckACL() fails and continues the loop when it didn't end. Adding a simple virObjectUnlock() and clearing the pointer ought to do.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
