perf sched: Do not delete session object prematurely
The session object is released prematurely when processing events for
latency command. The session's thread objects are used within the
output_lat_thread function.
Runnning following commands:
# perf sched record
# perf sched latency
the latter displays incorrect data and might cause access violation.
