When compiling the cgroup selftests with the following command:

make -C tools/testing/selftests/cgroup/

the compiler complains as below:

test_cpu.c: In function ‘test_cpucg_nice’: test_cpu.c:284:39: error: incompatible type for argument 2 of ‘hog_cpus_timed’ 284 | hog_cpus_timed(cpucg, param); | ^~~~~ | | | struct cpu_hog_func_param test_cpu.c:132:53: note: expected ‘void *’ but argument is of type ‘struct cpu_hog_func_param’ 132 | static int hog_cpus_timed(const char *cgroup, void *arg) | ~~~~~~^~~

Fix it by passing the address of param to hog_cpus_timed().
