powerpc/mm: Fix build warnings with CONFIG_TRANSPARENT_HUGEPAGE disabled 



Building with CONFIG_TRANSPARENT_HUGEPAGE disabled causes the following
build wearnings;

powerpc/arch/powerpc/include/asm/mmu-hash64.h: In function ‘__hash_page_thp’:
powerpc/arch/powerpc/include/asm/mmu-hash64.h:354: warning: no return statement in function returning non-void

This patch adds a return -1 to the static inline for __hash_page_thp()
to correct the warnings.
