kunit: Reset test status on each param iteration

Browse Source 
If we skip one parametrized test case then test status remains
SKIP for all subsequent test params leading to wrong reports:

$ ./tools/testing/kunit/kunit.py run \
	--kunitconfig ./lib/kunit/.kunitconfig *.example_params*
	--raw_output \

[ ] Starting KUnit Kernel (1/1)...

        # Subtest: example_params_test
    # example_params_test: initializing
    # example_params_test: cleaning up
        ok 1 example value 3 # SKIP unsupported param value 3
    # example_params_test: initializing
    # example_params_test: cleaning up
        ok 2 example value 2 # SKIP unsupported param value 3
    # example_params_test: initializing
    # example_params_test: cleaning up
        ok 3 example value 1 # SKIP unsupported param value 3
    # example_params_test: initializing
    # example_params_test: cleaning up
        ok 4 example value 0 # SKIP unsupported param value 0
    # example_params_test: pass:0 fail:0 skip:4 total:4
    ok 1 example_params_test # SKIP unsupported param value 0
    # example: exiting suite
ok 1 example # SKIP

Reset test status and status comment after each param iteration
to avoid using stale results.
