[libvirt] [PATCH 01/10] virProcessRunInMountNamespace: Report errors from child

[Michal Privoznik]

The comment to the function states that the errors from the child
process are reported. Well, the error buffer is filled with
possible error messages. But then it is thrown away. Among with
important error message from the child process.
