[PATCH 2/4] perf tests c2c: Report skip when the workload fails

The workload path leaves err at 0 and returns, so the test exits 0 and is
reported as a pass even though nothing was recorded and neither report
invocation ran. The check_c2c_support() path above it already sets err=2.

Set err=2 there as well so a failing workload is reported as a skip.
