With -Wmissing-prototypes enabled, there is a warning that
unpoison_slab_object() has no prototype, breaking the build with
CONFIG_WERROR=y:
mm/kasan/common.c:271:6: error: no previous prototype for 'unpoison_slab_object' [-Werror=missing-prototypes]
271 | void unpoison_slab_object(struct kmem_cache *cache, void *object, gfp_t flags,
| ^~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Mark the function as static, as it is not used outside of this
translation unit, clearing up the warning.
Fixes: 3f38c3c5bc40 ("kasan: save alloc stack traces for mempool")
