x86: Fix for cache computation on AMD legacy cpus.
Some legacy AMD CPUs and hypervisors have the _cpuid_ '0x8000_001D' set to Zero, thus resulting in zeroed-out computed cache values. This patch reintroduces the old way of cache computation as a fail-safe option to handle these exceptions. Fixed 'level4_cache_size' value through handle_amd().
