Ian Rogers a061a8ad3f perf test: Avoid sysfs state affecting fake events 
Icelake has a slots event, on my Skylakex I have CPU events in sysfs of
topdown-slots-issued and topdown-total-slots.

Legacy event parsing would try to use '-' to separate parts of an event
and so perf_pmu__parse_init sets 'slots' to be a
PMU_EVENT_SYMBOL_SUFFIX2.

As such parsing the slots event for a fake PMU fails as a
PMU_EVENT_SYMBOL_SUFFIX2 isn't made into the PE_PMU_EVENT_FAKE token.

Resolve this issue by test initializing the PMU parsing state before
every parse. This must be done every parse as the state is removes after
each parse_events.
