samples/bpf: xdp_redirect_cpu have not need for read_trace_pipe
The sample xdp_redirect_cpu is not using helper bpf_trace_printk. Thus it makes no sense that the --debug option us reading from /sys/kernel/debug/tracing/trace_pipe via read_trace_pipe. Simply remove it. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
