mm, slab: move prepare_slab_obj_exts_hook under CONFIG_MEM_ALLOC_PROFILING
The only place prepare_slab_obj_exts_hook() is currently being used is
from alloc_tagging_slab_alloc_hook() when CONFIG_MEM_ALLOC_PROFILING=y.
Move its definition under CONFIG_MEM_ALLOC_PROFILING to prevent unused
function warning for CONFIG_SLAB_OBJ_EXT=n case.
