[PATCH v2 1/4] trace-cmd reset: Bail out immediately if user provides an invalid option

trace_reset() does not care invalid command line options and carries on
execution. For instance, "trace-cmd reset -x" command successfully
completes the reset request (despite of "reset: invalid option -- 'x'"
warning). Thus, show the usage message and terminate execution instead
of running the reset routine.
