Daniel Bristot de Oliveira 02d89917ef rtla/timerlat_aa: Zero thread sum after every sample analysis
The thread thread_thread_sum accounts for thread interference
during a single activation. It was not being zeroed, so it was
accumulating thread interference over all activations.

It was not that visible when timerlat was the highest priority.
