perf_counter: fix threaded task exit
Flushing counters in __exit_signal() with irqs disabled is not
a good idea as perf_counter_exit_task() acquires mutexes. So
flush it before acquiring the tasklist lock.
(Note, we still need a fix for when the PID has been unhashed.)
[ Impact: fix crash with inherited counters ]
