[PATCH 5/9] virfile: Resolve Coverity RESOURCE_LEAK

[John Ferlan <jferlan@xxxxxxxxxx>]

With the virGetGroupList() change in place - Coverity further complains
that if we fail to virFork(), the groups will be leaked - which aha seems
to be the case. Adjust the logic to save off the -errno, free the groups,
and then return the value we saved
