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.
