x86/cpu/intel: Rename CPUID(0x2) descriptors iterator parameter

The CPUID(0x2) descriptors iterator has been renamed from:

for_each_leaf_0x2_entry()

to:

for_each_cpuid_0x2_desc()

since it iterates over CPUID(0x2) cache and TLB "descriptors", not
"entries".

In the macro's x86/cpu call-site, rename the parameter denoting the
parsed descriptor at each iteration from 'entry' to 'desc'.
