anv/perf: fixup counter/query mapping

The intel_perf_counter_pass::pass field is actually useless and
invalid.

Once you have mapped all the counters to all the metrics, the order of
the metrics capture is dictated by intel_perf_get_n_passes().

When reading values that is the order we should follow.
