[PATCH v5 08/15] kunit: tool: Don't overwrite test status based on subtest counts

Brendan Higgins, David Gow, Linus Torvalds
If a subtest itself reports success, but the outer testcase fails, the whole testcase should be reported as a failure. However the status is recalculated based on the test counts, overwriting the outer test result. Synthesize a failed test in this case to make sure the failure is not swallowed.
