[PATCH v2 10/11] powerpc/64s/slb: Make preload_add return type as void

["Ritesh Harjani (IBM)" <ritesh.list@gmail.com>]

We dropped preload_new_slb_context() & slb_setup_new_exec() in a
previous patch. That means we don't really need preload_add() return
type anymore. So let's make its return type as void.
