Fix man page for ppc64_cpu
Fix man page for ppc64_cpu

Currently there is a typo on ppc64_cpu manpage which causes the text
to be corrupted, not printing anything after this typo, as showed:

       --smt  Display the current smt setting for  the  system.  The
              .....
              threads online varies per core, or

As you can see, there is nothing else after the ", or" expression.

This patch simply fixes this typo, which makes the manpage render
correctly.
