[OPTIM] small optimization on session_process_counters()

Browse Source 
It was possible to slightly reduce the size and the number of
operations in session_process_counters(). Two 64 bit comparisons
were removed, reducing the code by 98 bytes on x86 due to the lack
of registers. The net observed performance gain is almost 2%, which
cannot be attributed to those optimizations, but more likely to
induced changes in code alignment in other functions.
