tools/x86/kcpuid: Protect against faulty "max subleaf" values
[ Upstream commit cf96ab1a966b87b09fdd9e8cc8357d2d00776a3a ]
Protect against the kcpuid code parsing faulty max subleaf numbers
through a min() expression. Thus, ensuring that max_subleaf will always
be ≤ MAX_SUBLEAF_NUM.
Use "u32" for the subleaf numbers since kcpuid is compiled with -Wextra,
which includes signed/unsigned comparisons warnings.
