Randconfig builds started warning about a missing function declaration
after set_memory_valid() is moved to a new file:
In file included from mm/kfence/core.c:26:
arch/arm64/include/asm/kfence.h:17:2: error: implicit declaration of function 'set_memory_valid' [-Werror,-Wimplicit-function-declaration]
Include the correct header again.
Fixes: 9e18ec3cfabd ("set_memory: allow querying whether set_direct_map_*() is actually enabled")
Fixes: 204555ff8bd6 ("arm64, kfence: enable KFENCE for ARM64")

(it should go via the mm tree with the other kfence patches)
