FROMLIST: kasan: fix build by including kernel.h

Browse Source 
The <linux/kasan.h> header relies on _RET_IP_ being defined, and had
been receiving that definition via inclusion of bug.h which includes
kernel.h. However, since f39650de68 that is no longer the case and get
the following build error when building CONFIG_KASAN_HW_TAGS on arm64:

  In file included from arch/arm64/mm/kasan_init.c:10:
  ./include/linux/kasan.h: In function 'kasan_slab_free':
  ./include/linux/kasan.h:230:39: error: '_RET_IP_' undeclared (first use in this function)
    230 |   return __kasan_slab_free(s, object, _RET_IP_, init);

Fix it by including kernel.h from kasan.h.
