kasan: fail non-kasan KUnit tests on KASAN reports
After the recent changes done to KUnit-enabled KASAN tests, non-KASAN KUnit tests stopped being failed when KASAN report is detected. Recover that property by failing the currently running non-KASAN KUnit test when KASAN detects and prints a report for a bad memory access. Note that if the bad accesses happened in a kernel thread that doesn't have a reference to the currently running KUnit-test available via current->kunit_test, the test won't be failed. This is a limitation of KUnit, which doesn't yet provide a thread-agnostic way to find the reference to the currenly running test.
