perf/core: Fix perf-stat / read()
In the zeal to adjust all event->state checks to include the new
REVOKED state, one adjustment was made in error. Notably it resulted
in read() on the perf filedesc to stop working for any state lower
than ERROR, specifically EXIT.
This leads to problems with (among others) perf-stat, which wants to
read the counts after a program has finished execution.
Fixes: da916e96e2de ("perf: Make perf_pmu_unregister() useable")
