In normal practice a virFirewallCmd should never have 0 args by the
time it gets to the Apply stage, but at some time while debugging one
of the other patches in this series, exactly that happened (due to a
bug that was since squashed), and having a check for it helped
debugging, so let's permanently check for it.
