LoongArch: Do not select HAVE_RUST when KASAN is enabled

Browse Source 
After commit 2625480a1b ("hardening: Default randstruct off with rust
for better allmodconfig support"), which allows Rust to be enabled for
allmodconfig, ARCH=loongarch allmodconfig starts failing with:

  error: kernel-address sanitizer is not supported for this target

  error: aborting due to 1 previous error

  make[4]: *** [rust/Makefile:741: rust/core.o] Error 1

For the same reason as the commit 84a0f7caaf ("ARM: Do not select
HAVE_RUST when KASAN is enabled"), do not select HAVE_RUST when KASAN
is enabled until the loongarch64-unknown-none-softfloat target in rustc
supports KASAN.
