Subject: [kvm-unit-tests patch v6 03/18] x86: pmu: Refine fixed_events[] names

In SDM the fixed counter is numbered from 0 but currently the
fixed_events names are numbered from 1. It would cause confusion for
users. So Change the fixed_events[] names to number from 0 as well and
keep identical with SDM.
