kfence: fix implicit function declaration

When building kfence the following error shows up:

In file included from mm/kfence/report.c:13:
arch/arm64/include/asm/kfence.h: In function `kfence_protect_page':
arch/arm64/include/asm/kfence.h:12:2: error: implicit declaration of function `set_memory_valid' [-Werror=implicit-function-declaration]
   12 |  set_memory_valid(addr, 1, !protect);
      |  ^~~~~~~~~~~~~~~~

Use the correct include both
f2b7c491916d ("set_memory: allow querying whether set_direct_map_*() is actually enabled")
and 4c4c75881536 ("arm64, kfence: enable KFENCE for ARM64") went in the
same day via different trees.
