[POWERPC] lparcfg: Remove useless buffer allocation
The 'data' member of proc_ppc64_lparcfg is unused, but the lparcfg module's init routine allocates 4K for it. Remove the code which allocates and frees this buffer. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
