[libvirt] [PATCH] openvzDomainDefineCmd: remove useless increment

[Jim Meyering]

Another dead store.
Refreshingly shallow.

The function below starts like this:

    static int
    openvzDomainDefineCmd(virConnectPtr conn,
                          const char *args[],
                          int maxarg, virDomainDefPtr vmdef)
    {
        int narg;
        int veid;
        int max_veid;

and there are no intervening uses of "max_veid".
