In kunit_log_test() pass the kfree_wrapper() function to kunit_add_action() instead of directly passing kfree().

This prevents a cast warning:

lib/kunit/kunit-test.c:565:25: warning: cast from 'void (*)(const void *)' to 'kunit_action_t *' (aka 'void (*)(void *)') converts to incompatible function type [-Wcast-function-type-strict]

564 full_log = string_stream_get_string(test->log);

565 kunit_add_action(test, (kunit_action_t *)kfree, full_log);
