arch/x86: Skip returning default leaf value as `0`
`cpu_get_cache_info_leaf()` function is responsible to report leaf
value for CPU that have support for deterministic cache cpuid. As per
available datasheets from AMD and Intel the supported CPUID leafs are
0x8000_001d for AMD and 0x04 for Intel. Hence, this CL skips returning
default leaf value as `0`.
TEST=Verified fixes: e2b5fee3b006 (arch/x86: smbios write 7 table using
deterministic cache functions) hang issue on ASRock E350M1.
