[libvirt] [PATCH] virnetdevbandwidthtest: Introduce some more tests
And while doing this, fix one error raised by coverity. With
current code, @actual_cmd is allowed to be NULL for the whole
run of testVirNetDevBandwidthSet. However, if something else
was expected, the @actal_cmd is passed to virtTestDifference
which dereference it immediately.
