Test: Remove test result from struct test_t

It is unnecessary to assign a dedicated test result structure in
each test description. Test framework can define a common
test_result_t and pass it to each test case.

This patch removed the test_result_t in struct test_t to decrease
16 bytes * numbers of test cases.
