[libvirt] [PATCH] vz: BUG: fix connecting hang in case of init failure

[Maxim Nestratov]

In case of prlsdkLoadDomains fails, vzOpenDefault should
clear connection privateData pointer every time its
memory is actually freed.
Also it is not necessary to call vzConnectClose if a call
to vzOpenDefault fails, because they both make cleanup of
connection privateData.
