[PATCH 8/9] virhostdevtest: Reset libvirt error on expected failure

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

If a libvirt error occurred during a test, then virTestRun()
reports it (regardless of test returning success or failure).
For instance, in this specific case, a hostdev is detached twice
and the second attempt is expected to fail. It does fail and
libvirt error is reported which is then printed onto stderr.
Insert virResetLastError() calls on appropriate places to avoid
that.
