When running parameterized tests, each test case is initialized with kunit_init_test(). This function takes the test_case->log as a parameter but it clears it via string_stream_clear() on each iteration.

This results in only the log from the last parameter being preserved in the test_case->log and the results from the previous parameters are lost from the debugfs entry.

Fix this by manually setting the param_test.log to the test_case->log after it has been initialized. This prevents kunit_init_test() from clearing the log on each iteration.
