test: sched_perf: add num queues optionHEADmaster
Added option to set number of queues per worker thread. Number of active queues affects usually scheduler performance. Signed-off-by: Petri Savolainen <petri.savolainen@linaro.org> Reviewed-by: Bill Fischofer <bill.fischofer@linaro.org> Signed-off-by: Maxim Uvarov <maxim.uvarov@linaro.org>
