Coverity complains that 'mode' isn't used - while a silly complaint is
there anything that could be done to just compare "mode" against an
"expected" (or perhaps unexpected value)?


247  	    }
248  	

(1) Event returned_pointer: 	Pointer "mode" returned by
"virJSONValueObjectGetString(args, "mode")" is never used.

249  	    if (!(mode = virJSONValueObjectGetString(args, "mode"))) {
250  	        ret = qemuMonitorReportError(test, "Missing shutdown mode");
