Rule 5.3 has the following headline:
"An identifier declared in an inner scope shall not hide an
identifier declared in an outer scope"

The declaration of local variable 'cpuid_leaf' causes
shadowing with the homonymous function to happen, therefore
the variable is renamed to avoid this.

No functional changes.
