Ahmed S. Darwish dacec3a324 tools/x86/kcpuid: Protect against faulty "max subleaf" values 
[ Upstream commit cf96ab1a96 ]

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.
