lsslot: Allow printing information of all possible cpus
lsslot: Allow printing information of all possible cpus

The lsslot command gathers information about all possible cpus on a
system but only prints information about cpus that are present. This
patch adds the ability to print information about all possible cpus
when the '-d 4' option is used.
