If we run ftracetest on the kernel with CONFIG_DYNAMIC_FTRACE=n, there is no set_ftrace_filter and all test cases are failed, because reset_ftrace_filter() returns an error. Let's check whether set_ftrace_filter exists in reset_ftrace_filter() and clean up only set_ftrace_notrace in initialize_ftrace().
