Subject: [PATCH 6/6] perf test: Do not set TEST_SKIP for record subtests

It now has 4 sub tests and one of them should run at least.
But once 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 tested are skipped but the remaining subtests are passed.

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