powerpc/64s/radix: Fix build failure with RADIX_MMU=n 

After merging the powerpc tree, today's linux-next build (powerpc64
allnoconfig) failed like this:

 arch/powerpc/mm/book3s64/pgtable.c:216:3:
 error: implicit declaration of function 'radix__flush_all_lpid_guest'

radix__flush_all_lpid_guest() is only declared for
CONFIG_PPC_RADIX_MMU which is not set for this build.

Fix it by adding an empty version for the RADIX_MMU=n case, which
should never be called.
