[PATCH v3 08/15] kasan: add compiler barriers to KUNIT_EXPECT_KASAN_FAIL

It might not be obvious to the compiler that the expression must be executed between writing and reading to fail_data. In this case, the compiler might reorder or optimize away some of the accesses, and the tests will fail. Add compiler barriers around the expression in KUNIT_EXPECT_KASAN_FAIL
