[PATCH 5.10 127/236] bpf, samples: Add missing mprog-disable to xdp_redirect_cpus optstring

[Greg Kroah-Hartman]

From: Matthew Cover <werekraken@xxxxxxxxx>

[ Upstream commit 34ad6d9d8c27293e1895b448af7d6cf5d351ad8d ]

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

Fix it and add the missing option character.
