[ Upstream commit 279d1a72c0f8021520f68ddb0a1346ff9ba1ea8c ]

Cédric pointed out that XIVE IPI information exported via sysfs
(debug/powerpc/xive) display empty lines for processors which are
not online.

Switch to using for_each_online_cpu() so that information is
displayed for online-only processors.
