[libvirt] [PATCH 2/3] objecteventtest: Check for virNetwork* return values
Lets not give a bad example and check for return values of
virNetwork* APIs called within the test. Even though it's
unlikely that any API will fail, it can happen. We're connected
to the test driver after all, and our API sequence is correct. So
test driver should fail only in case of bug or OOM.
