mm/slab_common: move declaration of __ksize() to mm/slab.h
__ksize() is only called by KASAN. Remove export symbol and move declaration to mm/slab.h as we don't want to grow its callers. Signed-off-by: Hyeonggon Yoo <42.hyeyoo@gmail.com> Reviewed-by: Vlastimil Babka <vbabka@suse.cz> Signed-off-by: Vlastimil Babka <vbabka@suse.cz>
