tools: bpftool: fix argument for p_err() in BTF do_dump()
The last argument passed to one call to the p_err() function is not
correct, it should be "*argv" instead of "**argv". This may lead to a
segmentation fault error if BTF id cannot be parsed correctly. Let's fix
this.
Fixes: c93cc69004dt ("bpftool: add ability to dump BTF types")
