Wang Qing bdc3ad9251 arch_topology: Do not set llc_sibling if llc_id is invalid 
commit 1dc9f1a66e upstream.

When ACPI is not enabled, cpuid_topo->llc_id = cpu_topo->llc_id = -1, which
will set llc_sibling 0xff(...), this is misleading.

Don't set llc_sibling(default 0) if we don't know the cache topology.
