perf_events: Check for filters on fixed counter events
Intel fixed counters do not support all the filters possible with a
generic counter. Thus, if a fixed counter event is passed but with
certain filters set, then the fixed_mode_idx() function must fail
and the event must be measured in a generic counter instead.
Reject filters are: inv, edge, cnt-mask.
