[libvirt] [PATCH] tests: Fix message for IP parse/format failures

[Roman Bolshakov]

Confusing message is printed when a parse/format sockettest fails. E.g.
there's a test that parses/formats ::ffff and the format fails like that:
  38) Test format ::ffff family AF_UNSPEC                               ...
  Offset 2
  Expect [0.0.255.255]
  Actual [ffff]

It should be instead:
  38) Test format ::ffff family AF_UNSPEC                               ...
  Offset 2
  Expect [ffff]
  Actual [0.0.255.255]
