File ppc64-diag.bug-931001_free_phandle_list.patch of Package ppc64-diag.636

During PRRN event handling we build a list of phandles for all the LMBs

From: Nathan Fontenot <nfont@linux.vnet.ibm.com>

on the system in order to correlate between drc indexes and their
phandle. This list is never free'ed. Failure to do so results in a list
that grows every time a PRRN event is handled.

After handling a PRRN event free the list of phandles.
