Julia Lawall a7df5c5e52 powerpc/pseries/dlpar: Eliminate use after free
dlpar_free_cc_nodes frees its argument, so dlpar_online_cpu should not be
called on the same value.  Skip over the call to dlpar_online_cpu by
jumping directly to out.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression E,E2;
@@

dlpar_free_cc_nodes(E)
...
(
  E = E2
|
* E
)
