[libvirt] [PATCH 1/3] tests: Return failures immediately in virErrorTestMsgs

[John Ferlan]

Rather than chancing calling strchr when @err_noinfo == NULL or
calling virErrorTestMsgFormatInfoOne when @err_info == NULL, both
of which would fail, let's just return -1 immediately when we
encounter an error.
