Subject: kasan: Mark unpoison_slab_object() as static
Date: Thu, 21 Dec 2023 19:00:42 +0100

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.
