Subject: [PATCH bpf-next] samples/bpf: xdp_redirect_cpu: Add mprog-disable to optstring.

Commit ce4dade7f12a ("samples/bpf: xdp_redirect_cpu: Load a eBPF program
on cpumap") added the following option, but missed adding it to optstring:
- mprog-disable: disable loading XDP program on cpumap entries

Add the missing option character.

Fixes: ce4dade7f12a ("samples/bpf: xdp_redirect_cpu: Load a eBPF program on cpumap")
