perf test: Do not set TEST_SKIP for record subtests

It now has 4 sub tests and at least one of them should run.

But once the TEST_SKIP (= 2) return value is set, it won't be
overwritten unless there's a failure.  I think we should return success
when one or more tests are skipped but the remaining subtests are
passed.

So update the test code not to set the err variable when it skips
the test.
