Subject: [PATCH 2/3] kselftest/filelock: Report each test in oftlocks
separately
The filelock test checks four different things but only reports an overall
status, convert to use ksft_test_result() for these individual tests. Each
test depends on the previous ones so we still bail out if any of them fail
but we get a bit more information from UIs parsing the results.
