Subject: [PATCH mm 08/22] kasan: check CONFIG_KASAN_KUNIT_TEST instead of CONFIG_KUNIT

From: Andrey Konovalov <andreyknvl@...gle.com>

Check the more specific CONFIG_KASAN_KUNIT_TEST config option when
defining things related to KUnit-compatible KASAN tests instead of
CONFIG_KUNIT.

Also put the kunit_kasan_status definition next to the definitons of
other KASAN-related structs.
