x86, efi, kasan: Fix build failure on !KASAN && KMEMCHECK=y kernels

With KMEMCHECK=y, KASAN=n we get this build failure:

  arch/x86/platform/efi/efi.c:673:3:    error: implicit declaration of function ‘memcpy’ [-Werror=implicit-function-declaration]
  arch/x86/platform/efi/efi_64.c:139:2: error: implicit declaration of function ‘memcpy’ [-Werror=implicit-function-declaration]
  arch/x86/include/asm/desc.h:121:2:    error: implicit declaration of function ‘memcpy’ [-Werror=implicit-function-declaration]

Don't #undef memcpy if KASAN=n.
