Sparse report:

target-ppc/mmu-hash64.c:353:9: warning: returning void-valued expression
target-ppc/mmu-hash64.c:620:9: warning: returning void-valued expression

Cc: Alexander Graf <agraf@suse.de>

Should we fix this kind of warnings? QEMU includes more than
60 lines of code which return a void expression.

I think it makes a lot of sense to fix these.

Thanks, applied to ppc-next (unfortunately after my pull request, so
it'll only go in after rc0).
