Thank you Stepehen on this, the reason why we specifically added to address 2 scenarios
 1. as pointed out by Wathsala where System Level Cache will be disabled; where L3 will be not available at all
 2. for version where hwloc does not detect the specific cache level.

By checking the NULL we can avoid such cases.

Note: I will recheck and add|remove this in v4
