x86/cacheinfo: Fix a -Wtype-limits warning

cpuinfo_x86.x86_model is an unsigned type, so comparing against zero
will generate a compilation warning:

  arch/x86/kernel/cpu/cacheinfo.c: In function 'cacheinfo_amd_init_llc_id':
  arch/x86/kernel/cpu/cacheinfo.c:662:19: warning: comparison is always true \
    due to limited range of data type [-Wtype-limits]

Remove the unnecessary lower bound check.
