xdp_cpumap_attach, in its current form, only checks that an xdp cpumap program can be executed, but not that it performs correctly the cpu redirect as configured by userspace (bpf_prog_test_run_opts will return success even if the redirect program returns an error) Add a check to ensure that the program performs the configured redirect as well. The check is based on a global variable incremented by a chained program executed only if the redirect program properly executes.
