x86/cpu/intel_cacheinfo: Remove redundant assignment to 'this_leaf'

The 'this_leaf' variable is assigned a value that is never
read and it is updated a little later with a newer value,
hence we can remove the redundant assignment.

Cleans up the following Clang warning:

  Value stored to 'this_leaf' is never read
