cpufreq: Don't remove sysfs link for policy->cpu

"cpufreq" directory in policy->cpu is never created using
sysfs_create_link(), but using kobject_init_and_add(). And so we
shouldn't call sysfs_remove_link() for policy->cpu().  sysfs stuff
for policy->cpu is automatically removed when we call kobject_put()
for dying policy.
