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.
