x86/intel_rdt: Protect info directory from removal The info directory and the per-resource subdirectories of the info directory have no reference to a struct rdtgroup in kn->priv. An attempt to remove one of those directories results in a NULL pointer dereference. Protect the directories from removal and return -EPERM instead of -ENOENT.
