[libvirt] [PATCH v2 1/6] openvz: Resolve Coverity FORWARD_NULL

[John Ferlan]

In openvzGetVPSUUID while parsing the conf_file, if "line" is for some
reason returned as NULL from a getline() call with a successful status,
then the subsequent call to strtok_r would attempt to reference the
'saveptr' which was initialized to NULL leading to an issue.

Altough getline() claims it would return an error, this does avoid
the problem and of course keep Coverity quiet
