Enabling KERNEL_KASAN exposes several missing symbols. As KASAN_SW_TAGS
is only implemented for arm64 CPUs and requires clang, it doesn't make
sense to make this a build option so just default to KASAN_GENERIC and
disable KASAN_SW_TAGS.
While at it, disable TEST_KASAN_MODULE in the generic 5.10 config.
Fixes build failures with KERNEL_KASAN enabled.
