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. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
