Papi counters don't work with reset and evaluate API's

[pagrubel]

A segmentation fault occurs if the API's for resetting and evaluating the counters is used as in hpx_homogenous_timed_task_spawn
// Reset performance counters (if specified on command line)
reset_active_counters();
.....do some work......
// Evaluate Performance Counters
evaluate_active_counters();
(This is probably not needed in the benchmark but I'm going to leave it there and make a new one without it so we have something to test for using them.)
Here are results for hpx_homogeneous_task_spawn hpx_homogeneous_timed_task_spawn

bin/hpx_homogeneous_timed_task_spawn --hpx:print-counter=/papi{locality#0/worker-thread#0}/PAPI_TLB_DM

Maciek, I assigned you for the sole purpose to get you in the loop. Feel free to un-assign yourself, if appropriate. In any case, any help would be very much appreciated.

OK, will take a look at it...
