I realize that this particular issue only exists until you switch to
using autoptr in patch 7, but you're technically introducing a bug
here. virCgroupFree() no longer clears the ptr to NULL, so when you
free cgroup_temp up above within this function, it is now a dangling
pointer, and then we try to free it again in the cleanup section.
Previously this cleanup call to virCgroupFree() was a no-op for all
non-error paths.
There are several other examples within this patch.
