From: Arnd Bergmann <arnd@arndb.de>

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.

Link: https://lkml.kernel.org/r/20210125125025.102381-1-arnd@kernel.org
Fixes: 9e18ec3cfabd ("set_memory: allow querying whether set_direct_map_*() is actually enabled")
Fixes: 204555ff8bd6 ("arm64, kfence: enable KFENCE for ARM64")
