Arnaldo Carvalho de Melo 25c5e67cdf perf tests record: Fail the test if the 'errs' counter is not zero
We were just checking for the 'err' variable, when we should really see
if there was some of the many checked errors that don't stop the test
right away.

Detected with clang 15.0.0:

  44    75.23 fedora:37       : FAIL clang version 15.0.0 (Fedora 15.0.0-2.fc37)

    tests/perf-record.c:68:16: error: variable 'errs' set but not used [-Werror,-Wunused-but-set-variable]
            int err = -1, errs = 0, i, wakeups = 0;
                          ^
    1 error generated.

The patch introducing this 'perf test' entry had that check:

  +       return (err < 0 || errs > 0) ? -1 : 0;

But at some point we lost that:

  -	  return (err < 0 || errs > 0) ? -1 : 0;
  +	  if (err == -EACCES)
  +               return TEST_SKIP;
  +	  if (err < 0)
  +               return TEST_FAIL;
  +	  return TEST_OK

Put it back.
