[libvirt] [PATCH 4/9] virutil: Resolve Coverity RESOURCE_LEAK
This ends up being a very bizarre false positive. With an assist from
eblake, the claim is that mgetgroups() could return a -1 value, but yet
still have a groups buffer allocated, yet the example shown doesn't
seem to prove that.
Rather than fret about it, by adding a well placed sa_assert() on the
returned *list value we can "assure" ourselves that the mgetgroups()
failure path won't signal this condition.
