Commit 8e0b634b1327 ("powerpc/64s: Do not allocate lppaca if we are not
virtualized") removed allocation of lppaca on non virtualized platform. But with
CONFIG_PPC_SPLPAR enabled, we do access lppaca non-virtualized platform in some
code paths.
Fix this but adding runtime check for virtualized platform.
